Kernel Tree For Xiaomi 11 Lite NE 5G

Chris Mason ee6e6504e1 Add a per-inode lock around btrfs_drop_extents ... btrfs_drop_extents is always called with a range lock held on the inode. But, it may operate on extents outside that range as it drops and splits them. This patch adds a per-inode mutex that is held while calling btrfs_drop_extents and while inserting new extents into the tree. It prevents races from two procs working against adjacent ranges in the tree. Signed-off-by: Chris Mason <chris.mason@oracle.com>		2008-09-25 11:04:04 -04:00
