Hello!
We recently upgraded our backup server kernel (rsync with snapshots and
compression) to Linus git master from yesterday (3.2-rc4+ 09d9673d53005)
that contains the btrfs for-linus as of yesterday. We've been seeing a
few warnings and bugs:

WARNING: at mm
We were occasionaly leaking space when running xfstest 269. This is because if
we failed to start the transaction in the truncate loop we'd just goto out, but
we need to break so that the inode is removed from the orphan list and the space
is properly freed. Thanks,

Running xfstests 269 with some tracing my scripts kept spitting out errors about
releasing bytes that we didn't actually have reserved. This took me down a huge
rabbit hole and it turns out the way we deal with reserved_extents is wrong,
we need to only be setting it if the reservation succeeds, o
The device statistics are written into the device tree with each
transaction commit. Only modified statistics are written.
When a filesystem is mounted, the device statistic for each involved
device are read from the device tree and used to initialize the
counters.

The goal is to detect when drives start to get an increased error rate,
when drives should be replaced soon. Therefore statistic counters are
added that count IO errors (read, write and flush). Additionally, the
software detected errors like checksum errors and corrupted blocks are
counted.

An ioctl interface is added to get the device statistic counters.
A second ioctl is added to atomically get and reset these counters.

Yes - only one delalloc worker is now present, but there were at least

Since we have the free space caches, btrfs_orphan_cleanup also runs for
the tree_root. Unfortunately this also cleans up the orphans used to mark
subvol deletions in progress.
Currently if a subvol deletion gets interrupted twice by umount/mount, the
deletion will not be continued and the space per
19 matches
