Subject: "No acl" entry put in client-side acl cache instead of "not cached"
|
|
References: 171059
|
|
|
|
When the acl of a file is not cached and only the default acl of that
|
|
file is requested, a NULL "no acl" entry is put in the client-side acl
|
|
cache of nfs instead of ERR_PTR(-EAGAIN) "not cached".
