Description of problem:
There is a bug in the client-side NFS caching which causes the ACLs on a NFS mounted directories to "disappear".

Version-Release number of selected component (if applicable):
kernel-2.9.9-42.EL and any newer

How reproducible:
always

Steps to Reproduce:
On a server side (whatever system):
1. Create a NFS export: e.g. write into /etc/exports something like this:
/tmp *(rw,no_root_squash)
2. Create a testing directory: mkdir /tmp/test1
3. Change its ACL somehow, e.g.: setfacl -m u:tsmetana:w /tmp/test1

On a client side (RHEL-4):
4. mount -t nfs <server>:/tmp -o rw /mnt/nfs_test
5. cd /mnt/nfs_test/test1
6. getfacl . (the output shows correct ACLs)
7. mkdir dir1
8. getfacl . (this output is different from the previous)

Actual results:
Only the default ACL is shown:
# file: .
# owner: root
# group: root
user::rwx
group::rwx
other::r-x

Expected results:
The correct ACLs is shown:
# file: .
# owner: root
# group: root
user::rwx
user:tsmetana:-w-
group::r-x
mask::rwx
other::r-x

Additional info:
This is a known bug that was fixed in the commit 4814f56d19137b3b9fa8e00e1d332b3683b950de NFSv3: Client-side nfsacl caching fix
