[PATCH] lightnvm: pblk: fix chunk close trace event check
From: Hans Holmberg
Date: Fri Oct 26 2018 - 04:12:57 EST
The check for chunk closes suffers from an off-by-one issue, leading
to chunk close events not being traced. Fix this.
Fixes: 4c44abf43d00 ("lightnvm: pblk: add trace events for chunk states")
