btrfs: un-deprecate ioctls START_SYNC and WAIT_SYNC (a5009d3a) · Commits · 戴 / test

The two ioctls START_SYNC and WAIT_SYNC were mistakenly marked as deprecated and scheduled for removal but we actualy do use them for 'btrfs subvolume delete -C/-c'. The deprecated thing in should have been just the async flag for subvolume creation. The deprecation has been added in this development cycle, remove it until it's time. Fixes: ("btrfs: Deprecate BTRFS_SUBVOL_CREATE_ASYNC flag") Signed-off-by:
