Subject: [PATCH 346/351] gfapi : Handle the path == "" glfs_resolve_at
|
|
|
d1681e |
|
|
|
d1681e |
Currently there is no check for path = "" in glfs_resolve_at.
|
|
|
d1681e |
So if application sends an empty path, then the function resolves
|
|
|
d1681e |
into the parent inode which is incorrect. Plus modified possible
|
|
|
d1681e |
of "path" with "origpath" in the same function.
