From 4c44abf43d00d81f5c648f376c436a9405980efc Mon Sep 17 00:00:00 2001 From: Hans Holmberg Date: Tue, 9 Oct 2018 13:11:52 +0200 Subject: lightnvm: pblk: add trace events for chunk states MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Introduce trace points for tracking chunk states in pblk - this is useful for inspection of the entire state of the drive, and real handy for both fw and pblk debugging.
