["Manuel Bouyer" <bouyer%netbsd.org@localhost>]

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
