[PATCH 00/12] btrfs: inode creation cleanups and fixes

[Omar Sandoval <osandov@osandov.com>]

From: Omar Sandoval <osandov@fb.com>

This series contains several cleanups and fixes for our inode creation
codepaths. The main motivation for this is preparation for fscrypt
support (in particular, setting up the fscrypt context at inode creation
time). But, it also reduces a lot of code duplication and fixes some
minor bugs, so it's worth getting in ahead of time.

Patch 12 is the main change, which unifies and simplifies all of our
inode creation codepaths. Patches 1-11 are small cleanups that I was
able to peel off of the big patch.

Thanks!

  btrfs: reserve correct number of items for unlink and rmdir
