********
This patch fixes several defects in AutoFS.
- Two diagnostic messages are corrected.
- A defect wherein auto-mount map files provided via NIS,
  and included via a "+" directive in a file, may not be processed by
  autofsmount.  The resulting symptom would be missing intercept mount points
  and failing auto-mounts for those cases.
- A problem that may lead to the timeout failure of auto-mount requests is
  fixed.   When the problem occurs, a large number of autofsd
  processes will exist, and will be waiting for a chance to process their 
  request.Their kernel stack will indicate they are sleeping for a lock within
  a CFS routine.
- AutoFS auto-mount failures due to the early termination
  of auto-mount inducing lookups, result in errors returned to operations
  generating such lookups. The early termination results from the receipt of an
  unexpected signal while the kernel is waiting a response from the
  autofsd daemon.  The scenario that exposed this defect involved SIGCHLD in
  which a parent process spawned a child, caused an auto-mount, and the child
  exited while the kernel was waiting for the auto-mount to complete.  This
  caused the auto-mount to fail.  Since this is timing-sensitive, one may or may
  not see this problem reproduce easily.
- If an auto-mount map entry specifies multiple possible sites from which to
  mount a remote filesystem, the current implementation may contact the same 
  system's mount daemon multiple times when checking for its responsiveness.  
  This patch eliminates such duplicate checks.
- The defect being fixed by this patch may result in multiply mounted, AutoFS
  auto-mounted, NFS file systems.  This results from a race condition that
  may occur when an auto-mount request associated with an indirect map entry
  is interrupted.  The filesystem in question can still be accessed as normal.
  Auto-Unmounts will, however, fail. Such failures will be logged in the
  daemon.log  .
- This patch fixes autofsd so that it will correctly account for symbolic links
  in the path specified by direct map entry keys, when attempting an unmount.
  Without this fix, any auto-mounted filesystems associated with this type
  of map entry will never get auto-unmounted.


PROBLEM: (94406) (PATCH ID: OSF540-079)
********
With ACLs enabled, non-root users may be denied access to autofs indirect 
and special mounted filesystems.  Non-root users may  also be denied access to 
other filesystems that don't support ACLs (i.e. cdfs) as well.  This patch 
corrects this problem.
