Subject: [PATCH] xfs_repair: initialize non-leaf finobt blocks with correct
|
|
magic
|
|
|
|
The free inode btree construction code in xfs_repair has a bug where
|
|
any non-leaf nodes outside of the leftmost block at the associated
|
|
level in the tree are incorrectly initialized with the inobt magic
|
|
value. Update the prop_ino_cursor() path responsible for growing the
|
|
non-leaf portion of the inode btrees to use the btnum of the
|
|
specific tree being generated rather than the hardcoded inode btree
|
|
type.
