a8ddac7 mutex: speed up generic mutex implementations - atomic operations which both modify the variable and return something imply full smp memory barriers before and after the memory operations involved (failing atomic_cmpxchg, atomic_add_unless, etc don't imply a barrier because they don't modify the target). See Documentation/atomic_ops.txt. So remove extra barriers and branches. - All architectures support atomic_cmpxchg. This has no relation to __HAVE_ARCH_CMPXCHG. We can just take the atomic_cmpxchg path unconditionally This reduces a simple single threaded fastpath lock+unlock test from 590 cycles to 203 cycles on a ppc970 system.

94b6da5 memcg: fix page_cgroup allocation page_cgroup_init() is called from mem_cgroup_init(). But at this point, we cannot call alloc_bootmem(). (and this caused panic at boot.) This patch moves page_cgroup_init() to init/main.c. Time table is following: == parse_args(). # we can trust mem_cgroup_subsys.disabled bit after this. .... cgroup_init_early() # "early" init of cgroup. .... setup_arch() # memmap is allocated. ... page_cgroup_init(); mem_init(); # we cannot call alloc_bootmem after this. .... cgroup_init() # mem_cgroup is initialized. == Before page_cgroup_init(), mem_map must be initialized. So, I added page_cgroup_init() to init/main.c directly. (*) maybe this is not very clean but - cgroup_init_early() is too early - in cgroup_init(), we have to use vmalloc instead of alloc_bootmem(). use of vmalloc area in x86-32 is important and we should avoid very large vmalloc() in x86-32. So, we want to use alloc_bootmem() and added page_cgroup_init() directly to init/main.c [akpm@linux-foundation.org: remove unneeded/bad mem_cgroup_subsys declaration] [akpm@linux-foundation.org: fix build] Acked-by: Balbir Singh <balbir@linux.vnet.ibm.com> Tested-by: Balbir Singh <balbir@linux.vnet.ibm.com> Signed-off-by: KAMEZAWA Hiroyuki <kamezawa.hiroyu@jp.fujitsu.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org> 23 October 2008, 15:55:02 UTC
be07c4e jbd: abort instead of waiting for nonexistent transactions The __log_wait_for_space function sits in a loop checkpointing transactions until there is sufficient space free in the journal. However, if there are no transactions to be processed (e.g. because the free space calculation is wrong due to a corrupted filesystem) it will never progress. Check for space being required when no transactions are outstanding and abort the journal instead of endlessly looping.

But by commit 95450f5a7e53d5752ce1a0d0b8282e10fe745ae0 "ext3: don't read inode block if the buffer has a write error"(*), BH_Uptodate flag can be set to inode buffers with BH_Write_EIO in order to avoid reading old inode data. So now, we have to test BH_Write_EIO flag of checkpointing inode buffers instead of BH_Uptodate. This patch does it.

2d7c820 ext3: add checks for errors from jbd If the journal has aborted due to a checkpointing failure, we have to keep the contents of the journal space. Otherwise, the filesystem will lose uncheckpointed metadata completely and become inconsistent. To avoid this, we need to keep needs_recovery flag if checkpoint has failed. With this patch, ext3_put_super() detects a checkpointing failure from the return value of journal_destroy(), then it invokes ext3_abort() to make the filesystem read only and keep needs_recovery flag. Errors from journal_flush() are also handled by this patch in some places.

4afe978 jbd: fix error handling for checkpoint io When a checkpointing IO fails, current JBD code doesn't check the error and continue journaling. This means latest metadata can be lost from both the journal and filesystem. This patch leaves the failed metadata blocks in the journal space and aborts journaling in the case of log_do_checkpoint(). To achieve this, we need to do: 1. don't remove the failed buffer from the checkpoint list where in the case of __try_to_free_cp_buf() because it may be released or overwritten by a later transaction 2. log_do_checkpoint() is the last chance, remove the failed buffer from the checkpoint list and abort the journal 3. when checkpointing fails, don't update the journal super block to prevent the journaled contents from being cleaned. For safety, don't update j_tail and j_tail_sequence either 4. when checkpointing fails, notify this error to the ext3 layer so that ext3 don't clear the needs_recovery flag, otherwise the journaled contents are ignored and cleaned in the recovery phase 5. if the recovery fails, keep the needs_recovery flag 6. prevent cleanup_journal_tail() from being called between __journal_drop_transaction() and journal_abort() (a race issue between journal_flush() and __log_wait_for_space() Signed-off-by: Hidehiro Kawai <hidehiro.kawai.ez@hitachi.com> Acked-by: Jan Kara <jack@suse.cz> Cc: <linux-ext4@vger.kernel.org> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org> 23 October 2008, 15:55:01 UTC

9e44af7 drm/i915: hold dev->struct_mutex and DRM lock during vblank ring operations To synchronize clip lists with the X server, the DRM lock must be held while looking at drawable clip lists. To synchronize with other ring access, the ring mutex must be held while inserting commands into the ring. Failure to do the first resulted in easy visual corruption when moving windows, and the second could have corrupted the ring with DRI2. Grabbing the DRM lock involves using the DRM tasklet mechanism, grabbing the ring mutex means potentially sleeping. Deal with both of these by always running the tasklet from a work handler. Also, protect from clip list changes since the vblank request was queued by making sure the window has at least one rectangle while looking inside, preventing oopses .

a1c1989 PCI: Workaround invalid P2P bridge bus numbers Some firmware fail to properly configure P2P bridges, leaving them with invalid bus numbers. In some cases, this happens on some embedded 4xx boards as the result of the kernel allocating different bus space than the firmware does to host bridges while not setting pcibios_assign_all_busses() for various reasons. In other cases, it can just be bogus firmware. This adds some sanity checking to the PCI probing code. If a bridge is found whose primary bus number doesn't match the bus it's sitting on, or whose secondary bus number not strictly above it's primary bus number, then the bridge bus numbers are deconfigured in the first pass of pci_scan_bridge() to be re-assigned in the second pass.

5fe6cc6 PCI: prevent duplicate slot names Prevent callers of pci_create_slot() from registering slots with duplicate names. This condition occurs most often when PCI hotplug drivers are loaded on platforms with broken firmware that assigns identical names to multiple slots. We now rename these duplicate slots on behalf of the user. If firmware assigns the name N to multiple slots, then: The first registered slot is assigned N The second registered slot is assigned N-1 The third registered slot is assigned N-2 etc. This is the permanent fix mentioned in earlier commits d6a9e9b4 and 167e782e (shpchp/pciehp: Rename duplicate slot name...). We take advantage of the new 'hotplug' parameter in pci_create_slot() to prevent a slot create/rename race between hotplug drivers and detection drivers. Scenario A: hotplug driver detection driver -------------- ---------------- pci_create_slot(hotplug=set) pci_create_slot(hotplug=NULL) The hotplug driver creates the slot with its desired name, and then releases the semaphore. Now, the detection driver tries to create the same slot, but it already exists. We don't care about renaming, so return the existing slot. Scenario B: hotplug driver detection driver -------------- ---------------- pci_create_slot(hotplug=NULL) pci_create_slot(hotplug=set) The detection driver creates the slot with name "X". Then the hotplug driver tries to create the same slot, but wants the name "Y" instead. We detect that we're trying to create the same slot and that we also want a rename, so rename the slot to "Y" and return. Scenario C: hotplug driver hotplug driver -------------- ---------------- pci_create_slot(hotplug=set) pci_create_slot(hotplug=set) Two separate hotplug drivers are attempting to claim the slot and are passing valid hotplug_slot args to pci_create_slot(). We detect that the slot already has a ->hotplug callback, prevent a rename, and return -EBUSY.

828f376 PCI: update pci_create_slot() to take a 'hotplug' param Slot detection drivers can co-exist with hotplug drivers. The names of the detected/claimed slots may be different depending on module load order. For legacy reasons, we need to allow hotplug drivers to override the slot name if a detection driver is loaded first (and they find the same slots). Creating and overriding slot names should be an atomic operation, otherwise you get a locking nightmare as various drivers race to call pci_create_slot(). pci_create_slot() is already serialized by grabbing the pci_bus_sem. We update the API and add a 'hotplug' param, which is: set if the caller is a hotplug driver NULL if the caller is a detection driver pci_create_slot() does not actually use the 'hotplug' parameter in this patch. A later patch will add the logic that uses it.

1359f27 PCI Hotplug core: add 'name' param pci_hp_register interface Update pci_hp_register() to take a const char *name parameter. The motivation for this is to clean up the individual hotplug drivers so that each one does not have to manage its own name. The PCI core should be the place where we manage the name. We update the interface and all callsites first, in a "no functional change" manner, and clean up the drivers later.

8dd7f80 PCI: add support for function level reset Sometimes, it's necessary to enable software's ability to quiesce and reset endpoint hardware with function-level granularity, so provide support for it. The patch implement Function Level Reset(FLR) feature following PCI-e spec. And this is the first step. We would add more generic method, like D0/D3, to allow more devices support this function. The patch contains two functions. pcie_reset_function() is the new driver API, and, contains some action to quiesce a device. The other function is a helper: pcie_execute_reset_function() just executes the reset for a particular device function. Current the usage model is in KVM. Function reset is necessary for assigning device to a guest, or moving it between partitions. For Function Level Reset(FLR), please refer to PCI Express spec chapter 6.6.2.

263c24a IB/ehca: Reject dynamic memory add/remove when ehca adapter is present Since the ehca device driver does not support dynamic memory add and remove operations, the driver must explicitly reject such requests in order to prevent unpredictable behaviors related to existing memory regions that cover all of memory being used by InfiniBand protocols in the kernel. The solution (for now at least) is to add a memory notifier to the ehca device driver and if a request for dynamic memory add or remove comes in, ehca will always reject it. The user can add or remove memory by hot-removing the ehca adapter, performing the memory operation, and then hot-adding the ehca adapter back.
