Subject[PATCH 0/2] lightnvm: patches for 4.15 on core
Date
These are 2 patches on the subsystem for 4.15.

The first one is a fix on the passtrhough path that enables fail fast,
just as it is done on standard nvme passtrough commands.

The second one implements a generic way to send sync. I/O from targets.
Trough time, we ended up having _many_ wait_for_completion()
constructions to implement sync. I/O, both on pblk and at the subsystem
level. One of the main issues - besides code replication - is that we
could not benefit from improvements on blk_execute_rq to prevent hangs.
This should fix it.

Javier González (2):
lightnvm: fail fast on passthrough commands
lightnvm: implement generic path for sync I/O
