Subject: [PATCH 0/9] recovery robustness improvements

From: Hans Holmberg <hans.holmberg@...xlabs.com>

This patchset improves the robustness of recovery - fixing a bunch of
issues that occurs when removing and re-creating a pblk instance.
It also adds a couple of debug-only prints to facilitate detection
of L2P table corruptions.

The patches apply on top of:
https://github.com/OpenChannelSSD/linux branch for-4.15/pblk

Hans Holmberg (9):
  lightnvm: pblk: prevent gc kicks when gc is not operational
  lightnvm: pblk: recover partially written lines correctly
  lightnvm: pblk: free full lines during recovery
  lightnvm: pblk: start gc if needed during init
  lightnvm: pblk: consider bad sectors in emeta during recovery
  lightnvm: pblk: shut down gc gracefully during exit
  lightnvm: pblk: add l2p crc debug printouts
  lightnvm: pblk: gc all lines in the pipeline before exit
  lightnvm: pblk: correct valid lba count calculation
