Subject: [PATCH 167/237] xfs: Fix termination loop for directory iteration
|
||
|
|
|
||
|
|
Directory iteration used wrong position (sizeof wrong structure) for
|
||
|
|
termination of iteration inside a directory block. Luckily the position
|
||
|
|
ended up being wrong by just 1 byte and directory entries are larger so
|
||
|
|
things worked out fine in practice. But fix the problem anyway.
