Subject: [PATCH 24/34] libacl: acl_set_file: Remove unnecesary racy check
|
||
|
|
|
||
|
|
Only directories can have default acls. This is checked in the kernel, and
|
||
|
|
unnecessarily also in acl_set_file. There is a window between checking the file
|
||
|
|
type and setting the acl, so the check in acl_set_file isn't even safe. Remove
|
||
|
|
it.
|
||
|
