[PATCH] Btrfs: fix broken nocow after balance
Balance will create reloc_root for each fs root, and it''s going to
record last_snapshot to filter shared blocks. The side effect of
setting last_snapshot is to break nocow attributes of files.
So it turns out that checking last_snapshot does not always ensure that
a node/leaf/file_extent is shared.
That''s why shared node/leaf needs to search extent tree for number of

[PATCH 2/4] Btrfs: fix deadlock on sb->s_umount when doing umount
The reason the deadlock is that:
Task Btrfs-cleaner
umount()
down_write(&s->s_umount)
sync_filesystem()
do auto-defragment and produce
lots of dirty pages
close_ctree()
wait for the end of

reserve space

Ceph on btrfs 3.4rc
After running ceph on XFS for some time, I decided to try btrfs again.
Performance with the current "for-linux-min" branch and big metadata
is much better. The only problem (?) I''m still seeing is a warning
that seems to occur from time to time:

[patch 00/65] Error handling patchset v3
Hi all -
Here''s my current error handling patchset, against 3.1-rc8. Almost all of
this patchset is preparing for actual error handling. Before we start in
on that work, I''m trying to reduce the surface we need to worry about. It
turns out that there is a ton of code that returns an error code but never
actually reports an error.
The patchset has grown to 65 patches. 46 of them

[PATCH v0 00/18] btfs: Subvolume Quota Groups
This is a first draft of a subvolume quota implementation. It is possible
to limit subvolumes and any group of subvolumes and also to track the amount
of space that will get freed when deleting snapshots.
The current version is functionally incomplete, with the main missing feature
being the initial scan and rescan of an existing filesystem.
I put some effort into writing an introduction into
