CVS commit: syssrc/sys



Module Name:    syssrc
Committed By:   thorpej
Date:           Fri Mar  8 21:42:00 UTC 2002

Modified Files:
        syssrc/sys/kern: subr_pool.c
        syssrc/sys/sys: pool.h

Log Message:
Add an optional "drain" client callback, which can be set by the new
pool_set_drain_hook().  This hook is called in three cases:
* When a pool has hit the hard limit, just before either erroring
  out or sleeping.
* When a backend allocator fails to allocate memory.
* Just before trying to reclaim pages in pool_reclaim().

This hook requests the client to try and free some items back to
the pool.
