1eff9d3 | Jens Axboe | 05 August 2016, 21:35:16 UTC | block: rename bio bi_rw to bi_opf Since commit 63a4cc24867d, bio->bi_rw contains flags in the lower portion and the op code in the higher portions. This means that old code that relies on manually setting bi_rw is most likely going to be broken. Instead of letting that brokeness linger, rename the member, to force old and out-of-tree code to break at compile time instead of at runtime. No intended functional changes in this commit.

Since we only care about whether it's a read or a write at that level, just pass in a bool 'is_write' parameter instead. Then we can also move op_is_write() and friends back under CONFIG_BLOCK protection.

Reverse mapping allows us to track the owner of a specific block on disk precisely. It is implemented as a set of btrees (one per allocation group) that track the owners of allocated extents. Effectively it is a "used space tree" that is updated when we allocate or free extents. i.e. it is coherent with the free space btrees we already maintain and never overlaps with them. This reverse mapping infrastructure is the building block of several upcoming features - reflink, copy-on-write data, dedupe, online metadata and data scrubbing, highly accurate bad sector/data loss reporting to users, and significantly improved reconstruction of damaged and corrupted filesystems. There's a lot of new stuff coming along in the next couple of cycles,a nd it all builds in the rmap infrastructure. As such, it's a huge chunk of new code with new on-disk format features and internal infrastructure. It warns at mount time as an experimental feature and that it may eat data (as we do with all new on-disk features until they stabilise). We have not released userspace suport for it yet - userspace support currently requires download from Darrick's xfsprogs repo and build from source, so the access to this feature is really developer/tester only at this point. Initial userspace support will be released at the same time kernel with this code in it is released. The new rmap enabled code regresses 3 xfstests - all are ENOSPC related corner cases, one of which Darrick posted a fix for a few hours ago. The other two are fixed by infrastructure that is part of the upcoming reflink patchset. This new ENOSPC infrastructure requires a on-disk format tweak required to keep mount times in check - we need to keep an on-disk count of allocated rmapbt blocks so we don't have to scan the entire btrees at mount time to count them. This is currently being tested and will be part of the fixes sent in the next week or two so users will not be exposed to this change" * tag 'xfs-rmap-for-linus-4.8-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/dgc/linux-xfs: (52 commits) xfs: move (and rename) the deferred bmap-free tracepoints xfs: collapse single use static functions xfs: remove unnecessary parentheses from log redo item recovery functions xfs: remove the extents array from the rmap update done log item xfs: in btree_lshift, only allocate temporary cursor when needed xfs: remove unnecesary lshift/rshift key initialization xfs: remove the get*keys and update_keys btree ops pointers xfs: enable the rmap btree functionality xfs: don't update rmapbt when fixing agfl xfs: disable XFS_IOC_SWAPEXT when rmap btree is enabled xfs: add rmap btree block detection to log recovery xfs: add rmap btree geometry feature flag xfs: propagate bmap updates to rmapbt xfs: enable the xfs_defer mechanism to process rmaps to update xfs: log rmap intent items xfs: create rmap update intent log items xfs: add rmap btree insert and delete helpers xfs: convert unwritten status of reverse mappings xfs: remove an extent from the rmap btree xfs: add an extent to the rmap btree ... | 06 August 2016, 13:50:36 UTC |

In the two host case the -r option must be used to specify the remote hostname (which must be SSH accessible and should probably have ssh-keys exchanged).

This could have caused some subtle corner case bugs when the link goes up and down quickly. Once that was fixed, there was found to be a race if the link was brought down then immediately up. The link_cleanup work would occasionally be scheduled after the next link up event. This would cancel the link_work that was supposed to occur and leave ntb_perf in an unusable state. To fix this we get rid of the link_cleanup work and put the actions directly in the link_down event.

This commit adds a 'link' file to the debugfs directory which reads boolean (Y or N) depending on the link status. Writing to the file change the link state using ntb_link_enable or ntb_link_disable. A 'link_event' file is also provided so an application can block until the link changes to the desired state. If the user writes a 1, it will block until the link is up.

717146a | Logan Gunthorpe | 20 June 2016, 19:15:09 UTC | ntb_tool: Postpone memory window initialization for the user In order to make the interface closer to the raw NTB API, this commit changes memory windows so they are not initialized on link up. Instead, the 'peer_trans*' debugfs files are introduced. When read, they return information provided by ntb_mw_get_range. When written, they create a buffer and initialize the memory window. The value written is taken as the requested size of the buffer (which is then rounded for alignment). Writing a value of zero frees the buffer and tears down the memory window translation. The 'peer_mw*' file is only created once the memory window translation is setup by the user. Additionally, it was noticed that the read and write functions for the 'peer_mw*' files should have checked for a NULL pointer.

Lots of race issues existed with the thread_cleanup. 2) The mutex allows us to ensure that threads are finished before tearing down the device or module. 3) Don't use kthread_stop when the threads can exit by themselves, as this is counter-indicated by the kthread_create documentation. Threads now wait for kthread_stop to occur. 4) Writing to the run file now blocks until the threads are complete. The test can then be safely interrupted by a SIGINT. Also, while I was at it: 5) debugfs_run_write shouldn't return 0 in the early check cases as this could cause debugfs_run_write to loop undesirably.

5a846ab | Rich Felker | 17 March 2016, 23:09:37 UTC | sh: add support for J-Core J2 processor At the CPU/ISA level, the J2 is compatible with SH-2, and thus the changes to add J2 support build on existing SH-2 support. However, J2 does not duplicate the memory-mapped SH-2 features like the cache interface. Instead, the cache interfaces is described in the device tree, and new code is added to be able to access the flat device tree at early boot before it is unflattened. Support is also added for receiving interrupts on trap numbers in the range 16 to 31, since the J-Core aic1 interrupt controller generates these traps. This range was unused but nominally for hardware exceptions on SH-2, and a few values in this range were used for exceptions on SH-2A, but SH-2A has its own version of the relevant code. No individual cpu subtypes are added for J2 since the intent moving forward is to represent SoCs with device tree rather than as hard-coded subtypes in the kernel. The CPU_SUBTYPE_J2 Kconfig item exists only to fit into the existing cpu selection mechanism until it is overhauled. Signed-off-by: Rich Felker <dalias@libc.org> | 05 August 2016, 03:29:31 UTC |
dd7fd3a | Rafael J. Wysocki | 05 August 2016, 00:38:44 UTC | ACPI / hotplug / PCI: Runtime resume bridges before bus rescans If a PCI bridge (or PCIe port) that is runtime-suspended gets an ACPI hotplug notification, such as a bus check, it has to be resumed before re-scanning the devices below it, or those devices will not be accessible and will be treated as hot-removed. Make that happen and let the bridge suspend again after the bus below it has been re-scanned. This is a replacement for commit 16468c783cb4 ("ACPI / hotplug / PCI: Runtime resume bridge before rescan") that has been reverted, because it introduced a system resume regression (due to missing bridge->pci_dev checks that are necessary in case the notification is targeted at the host bridge) and it is necessary for the code added by commit 006d44e49a25 ("PCI: Add runtime PM support for PCIe ports") to work as expected.

This makes return values on the client more consistent regardless of whenever the entry there is cached in the local cache or not. Another positive side effect is certain programs only expect EEXIST in that case even despite POSIX allowing any valid error to be returned.
