Subject: [PATCH 109/128] mount/fuse: never fail open(dir) with ENOENT
|
|
|
d1681e |
|
|
|
d1681e |
open(dir) being an operation on inode should never fail with
|
|
|
d1681e |
ENOENT. If gfid is not present, the appropriate error is ESTALE. This
|
|
|
d1681e |
will enable kernel to retry open after a revalidate lookup.
