[PATCH v2 00/16] 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 and encrypted
names 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.

Patches 1-3 are small fixes. Patches 5-12 are small cleanups. Patches
13-16 are the bulk of the change.

Based on misc-next.

Changes since v1 [1]:

- Split the big final patch into patches 3 and 13-16.
- Added Sweet Tea's reviewed-by to the remaining patches.
- Rebased on latest misc-next.

Thanks!
