Rafael debugged a resume-time hang (with oopses in workqueue handling) on his laptop that was due to the 'waker' workqueue entry being disconnected and then released without the workqueue entry having been synchronized. Several people were involved, with Oleg Nesterov doing a debugging patch showing what workqueue entry was corrupt etc. This was a regression introduced by commit 7bee549e ("Bluetooth: Add USB autosuspend support to btusb driver") as Rafael points out (not actually bisected, but it became clear once the bug was found).

There is a problem where iget5_locked will look for an inode, not find it, and then subsequently try to allocate it. Another CPU will have raced in and allocated the inode instead, so when iget5_locked gets the inode spin lock again and does a search, it finds the new inode. So it goes ahead and calls destroy_inode on the inode it just allocated. The problem is we don't set BTRFS_I(inode)->root until the new inode is completely initialized. This patch makes us set root to NULL when alloc'ing a new inode, so when we get to btrfs_destroy_inode and we see that root is NULL we can just free up the memory and continue on. This fixes the panic http://www.kerneloops.org/submitresult.php?number=812690 Thanks, Signed-off-by: NJosef Bacik <josef@redhat.com> Signed-off-by: NChris Mason <chris.mason@oracle.com>

On an FS where all of the space has not been allocated into chunks yet, the enospc can return enospc just because the existing metadata chunks are full. We get around this by allowing more metadata chunks to be allocated up to a certain limit, and finding the right limit is a little fuzzy. The problem is the reservations for delalloc would preallocate way too much of the FS as metadata. We need to start saying no and just force some IO to happen. But we also need to let a reasonable amount of the FS become metadata. This bumps the hard limit up, later releases will have a better system. Signed-off-by: NChris Mason <chris.mason@oracle.com>

Currently compressed IO does not deal with not having its entire extent able to be allocated. So if we have enough free space to allocate for the extent, but its not contiguous, it will fail spectacularly. This patch fixes this by falling back on uncompressed IO which lets us spread the delalloc extent across multiple extents. I tested this by making us randomly think the reservation had failed to make it fallback on the uncompressed io way and it seemed to work fine.

This patch changes a few things. Hopefully the comments are helpfull, but I'll try and be as verbose here. Problem: My fedora box was taking 1 minute and 21 seconds to boot with btrfs as root. Part of this problem was we pick the first block group we can find and start caching it, even if it may not have enough free space. The other problem is we only search for cached block groups the first time around, which we won't find any cached block groups because this is a newly mounted fs, so we end up caching several block groups during bootup, which with alot of fragmentation takes around 30-45 seconds to complete, which bogs down the system. So Solution: 1) Don't cache block groups willy-nilly at first. Instead try and figure out which block group has the most free, and therefore will take the least amount of time to cache. 2) Don't be so picky about cached block groups. The other problem is once we've filled up a cluster, if the block group isn't finished caching the next time we try and do the allocation we'll completely ignore the cluster and start searching from the beginning of the space, which makes us cache more block groups, which slows us down even more. So instead of skipping block groups that are not finished caching when we have a hint, only skip the block group if it hasn't started caching yet. There is one other tweak in here. Before if we allocated a chunk and still couldn't find new space, we'd end up switching the space info to force another chunk allocation. This could make us end up with way too many chunks, so keep track of this particular case. With this patch and my previous cluster fixes my fedora box now boots in 43 seconds, and according to the bootchart is not held up by our block group caching at all.

This patch fixes a problem where max_size can be set to 0 even though we filled the cluster properly. We set max_size to 0 if we restart the cluster window, but if the new start entry is big enough to be our new cluster then we could return with a max_size set to 0, which will mean the next time we try to allocate from this cluster it will fail. So set max_extent to the entry's size. Tested this on my box and now we actually allocate from the cluster after we fill it.

We use journal_info to tell if we're in a nested transaction to make sure we don't commit the transaction within a nested transaction. We use another method to see if there are any outstanding ioctl trans handles, so if we're starting one do not set current->journal_info, since it will screw with other filesystems.

Sometimes our start allocation hint when we cow a file can be either EXTENT_HOLE or some other such place holder, which is not optimal. So if we find that our em->block_start is one of these special values, check to see where the first block of the inode is stored, and use that as a hint. If that block is also a special value, just fallback on a hint of 0 and let the allocator figure out a good place to put the data.

Commit 9a1b64ca in 2.6.30 broke the error handling code in rawmidi_open_priv(). If only the output substream of a RawMIDI device has been opened and if this device is then opened with O_RDWR | O_APPEND and if the initialization of the input substream fails (either because of low memory or because the device driver's open callback fails), then the runtime structure of the already open output substream will be freed and all following writes through the first handle will cause snd_rawmidi_write() to use the NULL runtime pointer.
