Subject: [PATCH 0/4] Introduce trace events for pblk

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

This patchset adds trace events for tracking the internal state of
pblk. I've used the events extensively the last few months, and
they have proven very useful.

The patches depend on some of Javier's for-4.20 patches.
For ordering, see:

Branch: for-4.20/pblk
Remote: ssh://github.com/OpenChannelSSD/linux

Hans Holmberg (4):
  lightnvm: pblk: add trace events for chunk states
  lightnvm: pblk: add trace events for line state changes
  lightnvm: pblk: add trace events for pblk state changes
  lightnvm: pblk: add tracing for chunk resets
