[SRU Bionic/Focal/Hirsute/Impish 0/2] LP: #1947161 - ACL updates on OCFS2 are not revalidated

[Thadeu Lima de Souza Cascardo]

https://bugs.launchpad.net/bugs/1947161

[Impact]
When ACLs are updated on OCFS2, their caches are not revalidated, requiring remounts to be able to see the updates.

[Fix]
Upstream commits:
504ec37dfdfbf9c65166c51f7b12126d2a9b18dc ("ocfs2: fix remounting needed after setfacl command")
9c0f0a03e386f4e1df33db676401547e1b7800c6 ("ocfs2: drop acl cache for directories too")

[Test case]
On a single node:
setfacl -m u:user1:rwX dir1
getfacl dir1

On multiple nodes:
Node1:
getfacl dir1

Node2:
getfacl dir1

Node1:
setfacl -m u:user1:rwX dir1
getfacl dir1

Node2:
getfacl dir1

[Potential regression]
ACL changes on OCFS2 may stop working properly.
