a3fbbde Al Viro 07 November 2011, 21:21:26 UTC VFS: we need to set LOOKUP_JUMPED on mountpoint crossing Mountpoint crossing is similar to following procfs symlinks - we do not get ->d_revalidate() called for dentry we have arrived at, with unpleasant consequences for NFS4. Simple way to reproduce the problem in mainline: cat >/tmp/a.c <<'EOF' #include <unistd.h> #include <fcntl.h> #include <stdio.h> main() { struct flock fl = {.l_type = F_RDLCK, .l_whence = SEEK_SET, .l_len = 1}; if (fcntl(0, F_SETLK, &fl)) perror("setlk"); } EOF cc /tmp/a.c -o /tmp/test then on nfs4: mount --bind file1 file2 /tmp/test < file1 # ok /tmp/test < file2 # spews "setlk: No locks available"... What happens is the missing call of ->d_revalidate() after mountpoint crossing and that's where NFS4 would issue OPEN request to server. The fix is simple - treat mountpoint crossing the same way we deal with following procfs-style symlinks. I.e. set LOOKUP_JUMPED...

0bdfea8 Mandeep Baines 05 November 2011, 14:38:23 UTC forcedeth: Improve stats counters Rx byte count was off; instead use the hardware's count. Tx packet count was counting pre-TSO packets; instead count on-the-wire packets. Report hardware dropped frame count as rx_fifo_errors. - The count of transmitted packets reported by the forcedeth driver reports pre-TSO (TCP Segmentation Offload) packet counts and not the count of the number of packets sent on the wire. This change fixes the forcedeth driver to report the correct count. Fixed the code by copying the count stored in the NIC H/W to the value reported by the driver. - Count rx_drop_frame errors as rx_fifo_errors: We see a lot of rx_drop_frame errors if we disable the rx bottom-halves for too long. Normally, rx_fifo_errors would be counted in this case. The rx_drop_frame error count is private to forcedeth and is not reported by ifconfig or sysfs. The rx_fifo_errors count is currently unused in the forcedeth driver. It is reported by ifconfig as overruns. This change reports rx_drop_frame errors as rx_fifo_errors.

46bcfad Deepthi Dharwar 28 October 2011, 10:50:42 UTC cpuidle: Single/Global registration of idle states This patch makes the cpuidle_states structure global (single copy) instead of per-cpu. The statistics needed on per-cpu basis by the governor are kept per-cpu. This simplifies the cpuidle subsystem as state registration is done by single cpu only. Having single copy of cpuidle_states saves memory. Rare case of asymmetric C-states can be handled within the cpuidle driver and architectures such as POWER do not have asymmetric C-states. Having single/global registration of all the idle states, dynamic C-state transitions on x86 are handled by the boot cpu. Here, the boot cpu would disable all the devices, re-populate the states and later enable all the devices, irrespective of the cpu that would receive the notification first.

b25edc4 Deepthi Dharwar 28 October 2011, 10:50:24 UTC cpuidle: Remove CPUIDLE_FLAG_IGNORE and dev->prepare() The cpuidle_device->prepare() mechanism causes updates to the cpuidle_state[].flags, setting and clearing CPUIDLE_FLAG_IGNORE to tell the governor not to chose a state on a per-cpu basis at run-time. State demotion is now handled by the driver and it returns the actual state entered. Hence, this mechanism is not required. Also this removes per-cpu flags from cpuidle_state enabling it to be made global.

e978aa7 Deepthi Dharwar 28 October 2011, 10:50:09 UTC cpuidle: Move dev->last_residency update to driver enter routine; remove dev->last_state Cpuidle governor only suggests the state to enter using the governor->select() interface, but allows the low level driver to override the recommended state. The actual entered state may be different because of software or hardware demotion. Software demotion is done by the back-end cpuidle driver and can be accounted correctly. Current cpuidle code uses last_state field to capture the actual state entered and based on that updates the statistics for the state entered. Ideally the driver enter routine should update the counters, and it should return the state actually entered rather than the time spent there. The generic cpuidle code should simply handle where the counters live in the sysfs namespace, not updating the counters.

f7f71cf Rakib Mullick 06 November 2011, 15:18:17 UTC ACPI: Fix possible recursive locking in hwregs.c Calling pm-suspend might trigger a recursive lock in it's code path. In function acpi_hw_clear_acpi_status, acpi_os_acquire_lock holds the lock acpi_gbl_hardware_lock before calling acpi_hw_register_write(), then without releasing acpi_gbl_hardware_lock, this function calls acpi_ev_walk_gpe_list, which tries to hold acpi_gbl_gpe_lock. Both acpi_gbl_hardware_lock and acpi_gbl_gpe_lock are at same lock-class and which might cause lock recursion deadlock. Following patch fixes this scenario by just releasing acpi_gbl_hardware_lock before calling acpi_ev_walk_gpe_list.

This prevents use of dynamic debugging for out-of-tree modules once the next patch is applied. This condition was apparently intended to avoid a crash if a force- loaded module has an incompatible definition of dynamic debug structures. However, a administrator that forces us to load a module is claiming that it *is* compatible even though it fails our version checks. If they are mistaken, there are any number of ways the module could crash the system. As a side-effect, proprietary and other tainted modules can now use dynamic_debug.

The spec gives the reversed bit definition. But, following the spec also causes to change so many existing device configurations, thus we can't change it so easily for now. For 3.2-rc1, it's safer to revert this check (actually this patch comments out the code). We may re-introduced the fixed version once after the wider test-case coverages are done.

c06a0e1 Josef Bacik 04 November 2011, 23:56:02 UTC Btrfs: fix delayed insertion reservation We all keep getting those stupid warnings from use_block_rsv when running stress.sh, and it's because the delayed insertion stuff is being stupid. It's not the delayed insertion stuffs fault, it's all just stupid. When marking an inode dirty for oh say updating the time on it, we just do a btrfs_join_transaction, which doesn't reserve any space. This is stupid because we're going to have to have space reserve to make this change, but we do it because it's fast because chances are we're going to call it over and over again and it doesn't matter. Well thanks to the delayed insertion stuff this is mostly the case, so we do actually need to make this reservation. So if trans->bytes_reserved is 0 then try to do a normal reservation. If not return ENOSPC which will make the btrfs_dirty_inode start a proper transaction which will let it do the whole ENOSPC dance and reserve enough space for the delayed insertion to steal the reservation from the transaction. The other stupid thing we do is not reserve space for the inode when writing to the thing. Usually this is ok since we have to update the time so we'd have already done all this work before we get to the endio stuff, so it doesn't matter. But this is stupid because we could write the data after the transaction commits where we changed the mtime of the inode so we have to cow all the way down to the inode anyway. This used to be masked by the delalloc reservation stuff, but because we delay the update it doesn't get masked in this case. So again the delayed insertion stuff bites us in the ass. So if our trans->block_rsv is delalloc, just steal the reservation from the delalloc reserve. Hopefully this won't bite us in the ass, but I've said that before. With this patch stress.sh no longer spits out those stupid warnings (famous last words).

If we have an io error on a block, and later on end up reusing it, nobody ever clears PageError on those pages. During commit, we'll find PageError and think we had trouble writing the block, which will lead to aborts and other problems. This changes clean_tree_block and the btrfs writepage code to clear the PageError bit. In both cases we're either completely done with the page or the page has good stuff and the error bit is no longer valid.

663350a Josef Bacik 04 November 2011, 02:54:25 UTC Btrfs: be smarter about committing the transaction in reserve_metadata_bytes Because of the overcommit stuff I had to make it so that we committed the transaction all the time in reserve_metadata_bytes in case we had overcommitted because of delayed items. This was because previously we had no way of knowing how much space was reserved for delayed items. Now that we have the delayed_block_rsv we can check it to see if committing the transaction would get us anywhere. This patch breaks out the committing logic into a helper function that will check to see if committing the transaction would free enough space for us to get anything done.

It's because we will readjust global block rsv based on what is in use, which means we could end up discarding reservations that are for the delayed insertion stuff. So instead create a seperate block rsv for the delayed insertion stuff. This will also make it easier to debug problems with the delayed insertion reservations since we will know that only the delayed insertion code touches this block_rsv.
