Subject: [PATCH] init: do not create lat logs when not needed
Date: Mon, 17 Jan 2022 11:11:27 +0900	[thread overview]
Message-ID: <20220117021127.9259-1-damien.lemoal@wdc.com> (raw)

When any of the options disable_lat, disable_slat and disable_clat are
used, there is no need to create the lat log associated with the
disabled latency. In addition, when write_lat_log is also specified,
this change avoids the creation of empty latency log files.
