From 6685b357363bfe295e3ae73665014db4aed62c58 Mon Sep 17 00:00:00 2001 From: Mike Rapoport Date: Sun, 7 Oct 2018 11:31:51 +0300 Subject: [PATCH] percpu: stop leaking bitmap metadata blocks The commit ca460b3c9627 ("percpu: introduce bitmap metadata blocks") introduced bitmap metadata blocks. These metadata blocks are allocated whenever a new chunk is created, but they are never freed. Fix it.
