    sys/ufs/ufs          dirhash.h ufs_dirhash.c 
  Log:
  SVN rev 193375 on 2009-06-03 09:44:22Z by snb
  
  Add vm_lowmem event handler for dirhash. This will cause dirhashes to be
  deleted when the system is low on memory. This ought to allow an increase to
  vfs.ufs.dirhash_maxmem on machines that have lots of memory, without
  degrading performance by having too much memory reserved for dirhash when
  other things need it. The default value for dirhash_maxmem is being kept at
  2MB for now, though.
  
  This work was mostly done during the 2008 Google Summer of Code.
