Subject: [PATCH 3/3] ext4: add needed paramter to, ext4_mb_discard_preallocations trace
Date: Fri, 24 Jul 2020 10:58:18 +0800 [thread overview]
Message-ID: <0afd7706-aee2-cc23-7558-a60e39ac96a8@gmail.com> (raw)
Add the needed value to ext4_mb_discard_preallocations trace, so
we can more easily observe the requested number of trim.
