  21  * This module supports JFS (POSIX) ACLs on VxFS (Veritas * Filesystem).
  22  * These are available on HP-UX 11.00 if JFS 3.3 is installed. 
  23  * On HP-UX 11i (11.11 and above) these ACLs are supported out of
  24  * the box.
  25  *
  26  * There is another form of ACLs on HFS. These ACLs have a
  27  * completely different API and their own set of userland tools.
  28  * Since HFS seems to be considered deprecated, HFS acls
  29  * are not supported. (They could be supported through a separate
  30  * vfs-module if there is demand.)

  33 /* =================================================================
  34  * NOTE:
  35  *
  36  * The original hpux-acl code in lib/sysacls.c was based upon the
  37  * solaris acl code in the same file. Now for the new modularized
  38  * acl implementation, I have taken the code from vfs_solarisacls.c
  39  * and did similar adaptations as were done before, essentially
  40  * reusing the original internal aclsort functions.
  41  * The check for the presence of the acl() call has been adopted, and
  42  * a check for the presence of the aclsort() call has been added.
