Subject[GIT PULL 00/58] LightNVM updates for 4.15
Date
Hi Jens,

A couple of patches for 4.15.

Javier has improved garbage collection, statistics, memory pool usage,
and added support for single LUN configurations. He also made a lot of
bug fixes and cleanup patches.

Rakesh have been fixing up a lot of subsystem bugs with respect to
loading and unloading pblk, cleanup of memory pools, and a couple of
fixes spread across the lightnvm subsystem and pblk.

Hans has been looking into garbage collection, and shutting it
down gracefully when pblk is unloaded.

Please pull from the for-4.15/for-jens branch or apply the patches
posted with this thread:

https://github.com/OpenChannelSSD/linux.git for-4.15/for-jens

Thanks,
Matias
