Subject: [PATCH] xfs_repair: tag inobt vs finobt errors properly
|
|
|
48cf7c |
|
|
|
48cf7c |
Amend the generic inode btree block scanner function to tag correctly
|
|
|
48cf7c |
which tree it's complaining about. Previously, dubious finobt headers
|
|
|
48cf7c |
would be attributed to the "inode btree", which is at best ambiguous
|
|
|
48cf7c |
and misleading at worst.
