2011-09-01xfs: fix ->write_inode return valuesChristoph Hellwig1-25/+9
Currently we always redirty an inode that was attempted to be written out synchronously but has been cleaned by an AIL pushed internall, which is rather bogus. Fix that by doing the i_update_core check early on and return 0 for it. Also include async calls for it, as doing any work for those is just as pointless. While we're at it also fix the sign for the EIO return in case of a filesystem shutdown, and fix the completely non-sensical locking around xfs_log_inode.

2011-09-01xen: use maximum reservation to limit amount of usable RAMDavid Vrabel1-0/+19
Use the domain's maximum reservation to limit the amount of extra RAM for the memory balloon. This reduces the size of the pages tables and the amount of reserved low memory (which defaults to about 1/32 of the total RAM). On a system with 8 GiB of RAM with the domain limited to 1 GiB the kernel reports: Before: Memory: 627792k/4472000k available After: Memory: 549740k/11132224k available A increase of about 76 MiB (~1.5% of the unused 7 GiB). The reserved low memory is also reduced from 253 MiB to 32 MiB. The total additional usable RAM is 329 MiB. For dom0, this requires at patch to Xen ('x86: use 'dom0_mem' to limit the number of pages for dom0') (c/s 23790) CC: stable@kernel.org Signed-off-by: David Vrabel <david.vrabel@citrix.com> Signed-off-by: Konrad Rzeszutek Wilk <konrad.wilk@oracle.com>
2011-08-31xfs: fix xfs_mark_inode_dirty during umountChristoph Hellwig1-3/+11
During umount we do not add a dirty inode to the lru and wait for it to become clean first, but force writeback of data and metadata with I_WILL_FREE set. Currently there is no way for XFS to detect that the inode has been redirtied for metadata operations, as we skip the mark_inode_dirty call during teardown. Fix this by setting i_update_core nanually in that case, so that the inode gets flushed during inode reclaim. Alternatively we could enable calling mark_inode_dirty for inodes in I_WILL_FREE state, and let the VFS dirty tracking handle this. I decided against this as we will get better I/O patterns from reclaim compared to the synchronous writeout in write_inode_now, and always marking the inode dirty in some way from xfs_mark_inode_dirty is a better safetly net in either case.

2011-08-31ext4: remove i_mutex lock in ext4_evict_inode to fix lockdep complainingJiaying Zhang3-4/+18
The i_mutex lock and flush_completed_IO() added by commit 2581fdc810 in ext4_evict_inode() causes lockdep complaining about potential deadlock in several places. In most/all of these LOCKDEP complaints it looks like it's a false positive, since many of the potential circular locking cases can't take place by the time the ext4_evict_inode() is called; but since at the very least it may mask real problems, we need to address this. This change removes the flush_completed_IO() and i_mutex lock in ext4_evict_inode(). Instead, we take a different approach to resolve the software lockup that commit 2581fdc810 intends to fix. Rather than having ext4-dio-unwritten thread wait for grabing the i_mutex lock of an inode, we use mutex_trylock() instead, and simply requeue the work item if we fail to grab the inode's i_mutex lock. This should speed up work queue processing in general and also prevents the following deadlock scenario: During page fault, shrink_icache_memory is called that in turn evicts another inode B. Inode B has some pending io_end work so it calls ext4_ioend_wait() that waits for inode B's i_ioend_count to become zero. However, inode B's ioend work was queued behind some of inode A's ioend work on the same cpu's ext4-dio-unwritten workqueue. As the ext4-dio-unwritten thread on that cpu is processing inode A's ioend work, it tries to grab inode A's i_mutex lock. Since the i_mutex lock of inode A is still hold before the page fault happened, we enter a deadlock. Signed-off-by: Jiaying Zhang <jiayingz@google.com> Signed-off-by: "Theodore Ts'o" <tytso@mit.edu>

2011-08-31perf_event: Fix broken calc_timer_values()Eric B Munson1-2/+2
We detected a serious issue with PERF_SAMPLE_READ and timing information when events were being multiplexing. Samples would have time_running > time_enabled. That was easy to reproduce with a libpfm4 example (ran 3 times to cause multiplexing on Core 2): $ syst_smpl -e uops_retired:freq=1 & $ syst_smpl -e uops_retired:freq=1 & $ syst_smpl -e uops_retired:freq=1 & IIP:0x0000000040062d ...

It turns out the bug was introduced by the following commit: commit c4794295917ebeda8013b6cb9c8d71ab4f74a1fa events: Move lockless timer calculation into helper function The parameters of the function got reversed yet the call sites were not updated to reflect the change. That lead to time_running and time_enabled being swapped. That had no effect when there was no multiplexing because in that case time_running = time_enabled but it would show up in any other scenario.

2011-08-30md: fix clearing of 'blocked' flag in the presence of bad blocks.NeilBrown1-1/+1
When the 'blocked' flag on a device is cleared while there are unacknowledged bad blocks we must fail the device. This is needed for backwards compatability of the interface. The code currently uses the wrong test for "unacknowledged bad blocks exist". Change it to the right test. Signed-off-by: NeilBrown <neilb@suse.de>
