Subject: [PATCH 0/9] Switch defines to enums
Date: Tue, 27 Nov 2018 20:53:38 +0100	[thread overview]
Message-ID: <cover.1543348078.git.dsterba@suse.com> (raw)

This is motivated by a merging mistake that happened a few releases ago.
Two patches updated BTRFS_FS_* flags independently to the same value,
git did not see any direct merge conflict. The two values got mixed at
runtime and caused crash.

Update all #define sequential values, the above merging problem would
not happen as there would be a conflict and the enum value
auto-increment would prevent duplicated values anyway.

David Sterba (9):
  btrfs: switch BTRFS_FS_STATE_* to enums
  btrfs: switch BTRFS_BLOCK_RSV_* to enums
  btrfs: switch BTRFS_FS_* to enums
  btrfs: switch BTRFS_ROOT_* to enums
  btrfs: swtich EXTENT_BUFFER_* to enums
  btrfs: switch EXTENT_FLAG_* to enums
  btrfs: switch BTRFS_*_LOCK to enums
  btrfs: switch BTRFS_ORDERED_* to enums
  btrfs: drop extra enum initialization where using defaults
