[PATCH v2 0/2] zram: fix backing device setup issue

Posted by Kairui Song 1 month ago

From: Kairui Song <kasong@tencent.com>

This series fixes two bugs of backing device setting:

- ZRAM should reject using a zero sized (or the uninitialized ZRAM
  device itself) as the backing device.
- Fix backing device leaking when removing a uninitialized ZRAM
  device.
