Subject: [GIT PULL 03/21] lightnvm: pblk: fix chunk close trace event check
Date: Tue, 11 Dec 2018 20:16:09 +0100 [thread overview]
Message-ID: <20181211191627.15542-4-mb@lightnvm.io> (raw)
In-Reply-To: <20181211191627.15542-1-mb@lightnvm.io>
From: Hans Holmberg <hans.holmberg@cnexlabs.com>
The check for chunk closes suffers from an off-by-one issue, leading
to chunk close events not being traced.
Fixes: 4c44abf43d00 ("lightnvm: pblk: add trace events for chunk states")
