[0/4,RESEND] btrfs: fix property bugs

Message

Anand Jain April 2, 2019, 10:07 a.m. UTC

1/4 Fixes a bug that we were applying an incomplete string zstd.
2/4 Fixes a bug that the compression property gets reset to NULL after a
    failed attempt to change the compression parameter on the object.
3/4 preparatory patch so that btrfs_set_prop_trans() can be merged with
    btrfs_set_prop() in 4/4.
4/4 Fixes a bug that we were incrementing the generation even when the
    property validation check failed.

3/4 and 4/4 are only added here.

Anand Jain (4):
  btrfs: fix zstd compression parameter
  btrfs: fix vanished compression property after failed set
  btrfs: open code btrfs_set_prop in inherit_prop
  btrfs: fix property validate fail should not increment generation
