Module Name: src
Committed By: maxv

Modified Files:
src/sys/kern: subr_pool.c
Log Message:
Initialize pp->pr_redzone to false. For some reason with KUBSAN GCC does
not eliminate the unused branch in pr_item_linkedlist_put(), and this
leads to a unused uninitialized access which triggers KUBSAN messages.
