[PATCH 0/4] btrfs: out-of-band (aka offline) dedupe v4
Hi,
The following series of patches implements in btrfs an ioctl to do
out-of-band deduplication of file extents.
To be clear, this means that the file system is mounted and running, but the
dedupe is not done during file writes, but after the fact when some
userspace software initiates a dedupe.
The primary patch is loosely based off of one sent by Josef Bacik back
in January, 2011.

[PATCH 0/9] remove i_alloc_sem V2
i_alloc_sem has always been a bit of an odd "lock". It''s the only remaining
rw_semaphore that can be released by a different thread than the one that
locked it, and it''s use case in the core direct I/O code is more like a
counter given that the writers already have external serialization.
This series removes it in favour of a simpler counter scheme, thus getting
rid
