[PATCH 15/18] lightnvm: pblk: fix in case of lack of lines

From: Igor Konopko <hidden>
Date: 2019-03-14 16:09:13
Subsystem: the rest · Maintainer: Linus Torvalds

In case when mapping fails (called from writer thread) due to lack of
lines, currently we are calling pblk_pipeline_stop(), which waits
for pending write IOs, so it will lead to the deadlock. Switching
to __pblk_pipeline_stop() in that case instead will fix that.
