PROBLEM:    (CLD EVT102273,SPR VNO100100,QAR 55615)  (Patch ID: OSF375-350454)
********
This patch fixes a problem in which a filesystem cannot be unmounted.
The system displays a "Device busy" error message.

PROBLEM:        (QAR 59319, QAR 57562, QAR 57781)       (Patch ID: OSF375-148)
********
This patch fixed several problems with vfs file locking that could cause
a crash including the file lock adjust logic, delete sleep lock logic,
dead file lock logic, check/change granted logic, and insert file lock
logic.

The crash output might look something like:

PROBLEM:        (MCGMC1645, QAR 60270)  (Patch ID: OSF375-158)
********
This patch fixes a kernel memory fault panic in purge_fs_locks.
This problem is normally only seen on ASE or TruCluster systems.

A sample stack trace may look like:

  0 stop_secondary_cpu()
  1 panic("event_timeout: panic request")
  2 event_timeout()
  3 xcpu_puts()
  4 printf()
  5 panic("kernel memory fault")
  6 trap()
  7 _XentMM()
  8 purge_fs_locks()
  9 fcntl()
  10 syscall()
  11 _Xsyscall()
