[NFS-Ganesha-Support] Unable to delete last ACE entry of an ACL on FSAL_VFS with ENABLE_VFS_DEBUG_ACL as ON

Hello all, We are trying to use ACL functionality for FSAL_VFS and seeing the following issue while deleting the ACE entries. 1. Get/List file ACL -bash-4.2$ nfs4_getfacl abc # file: abc A::dev1:rxtTncy A::sub:rxtTncy 2. Delete specified ACE entry from the ACL and check -bash-4.2$ nfs4_setfacl -x A::dev1:RXT abc -bash-4.2$ nfs4_getfacl abc # file: abc A::sub:rxtTncy 3. Delete the last ACE bash-4.2$ nfs4_setfacl -x A::sub:RXT abc 4. Check if the last ACE is deleted and it's not. -bash-4.2$ nfs4_getfacl abc # file: abc A::sub:rxtTncy Inspite of deleting the last ACE, the nfs4_getfacl still shows the deleted ACE. Could anyone help and let us know if we are missing something here? Thanks, Subhash
