The following file(s) were checked into:
  bonnie.engr.sgi.com:/isms/slinx/2.4.x-xfs

cmd/acl/libacl/acl.c - 1.3
        - Don't incorrectly override the errno with the wrong 
          error number - the _syscall macro sets errno.

cmd/xfstests/051 - 1.2
        - If the syscall for acl_get/acl_set returns ENOSYS and
          hence the ACLs have been config'ed off,
          then don't run the test.

cmd/xfstests/common.rc - 1.3
        - Minor addition to output notrun msg in case one
          wants to run test from command line instead of
          check.
