From 0202ce8a90efdc81600e7bf9712d8c324081a924 Mon Sep 17 00:00:00 2001 From: Zdenek Kabelac Date: Wed, 8 Nov 2017 13:44:55 +0100 Subject: md: release allocated bitset sync_set Patch fixes kmemleak on md_stop() path used likely only by dm-raid wrapper. Code of md is using mddev_put() where both bitsets are released however this freeing is not shared. Also set NULL to bio_set and sync_set pointers just like mddev_put is doing.
