 Module Name:	src
 Committed By:	bouyer
 Date:		Mon May 26 08:32:11 UTC 2025
 
 Modified Files:
 	src/sys/kern: subr_pool.c
 
 Log Message:
 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
