[PATCH] mm/mempool: Avoid KASAN marking mempool posion checks as use-after-free

When removing an element from the mempool, mark it as unpoisoned in KASAN before verifying its contents for SLUB/SLAB debugging. Otherwise KASAN will flag the reads checking the element use-after-free writes as use-after-free reads. Signed-off-by: Matthew Dawson --- mm/mempool.c | 2 +- 1 file
