    doc                  locking.txt 
  Log:
  - fastlock: optimizations (in general a "nicer" spin on the lock for the other
    cpus) and cleanups for sparc, sparc64, armv6 (nosmp for now), ppc*, mips*
  - fastlock: alpha: replace the cond. jump backward with a
    cond. jump forward and then jump backward (because a cond. jump with
    a negative relative offset is always predicted as taken and we want it
    to be predicted as not taken)
  - fastlock: sparc (32) smp support
  - lock_ops.h: introduced lock_try and lock_set_try (non-blocking
    lock_*_get versions, returns -1 if it failed to get the lock and 0 if it
    succeeds), for all the supported locking methods (fast_lock, pthread_mutex,
     posix_sem, sysv_sems)
  - updated locking doc.
