 Modified Files:
 	src/sys/kern [netbsd-9]: subr_pool.c
 
 Log Message:
 Pull up following revision(s) (requested by bouyer in ticket #1956):
 
 	sys/kern/subr_pool.c: revision 1.295
 
 Never call pr_drain_hook from pool_allocator_alloc().
 
 In the PR_WAITOK case it's called from pool_reclaim
 
 In the !PR_WAITOK case we're holding the pool lock and if the drain hook
   wants kernel_lock we may deadlock with another thread holding
   kernel_lock and calling pool_get().
 
 Fixes PR kern/59411
