Module Name:	src
Committed By:	thorpej
Date:		Sat Jun 18 01:34:03 UTC 2005

Modified Files:
	src/sys/kern: subr_pool.c

Log Message:
Fix some locking issues:
- Make the locking rules for pr_rmpage() sane, and don't modify fields
  protected by the pool lock without actually holding it.
- Always defer freeing the pool page to the back-end allocator, to avoid
  invoking the pool_allocator with the pool locked (which would violate
  the pool_allocator -> pool locking order).
- Fix pool_reclaim() to not violate the pool_cache -> pool locking order
  by using a trylock.
