Subject: [PATCH net v2 0/1] atm: mpoa: Fix UAF on qos_head list in procfs

This series fixes a use-after-free on qos_head list in net/atm/mpc.c by
serializing add/search/delete/show paths with a mutex.

Changes since v1:
- resend using git send-email (previous patch got mangled)
- add Closes tag to satisfy checkpatch
- include trimmed KASAN report in commit message
