[ Upstream commit 64708539cd23b31d0f235a2c12a0cf782f95908a ]
A few places we intermix btrfs_inode_lock with a inode_unlock, and some places we just use inode_lock/inode_unlock instead of btrfs_inode_lock.
None of these places are using this incorrectly, but as we adjust some of these callers it would be nice to keep everything consistent, so convert everybody to use btrfs_inode_lock/btrfs_inode_unlock.
