After this commit, I am afraid access(2) on NFS may not work correctly.
The scenario based upon my guess.
- access(2) overrides the credentials.
- calls inode_permission() -- ... -- generic_permission() --
  ns_capable().
- while the old ns_capable() calls security_capable(current_cred()), the
  new ns_capable() calls has_ns_capability(current) --
  security_capable(__task_cred(t)).

current_cred() returns current->cred which is effective (overridden)
credentials, but __task_cred(current) returns current->real_cred (the
NFSD's credential). And the overridden credentials by access(2) lost.

Is my guess correct?
