Subject: [PATCH 1/4] scsi: target: direct completion support
Date: Sun, 22 Feb 2026 17:27:00 -0600 [thread overview]
Message-ID: <20260222232946.7637-1-michael.christie@oracle.com> (raw)
The following patches made over Linus's current tree allow users
to tell the target layer to perform direct completions instead of
always deferring to LIO's completion workqueue. When the frontend
driver already has multiple worker threads (or you are doing
a LUN per target with a single thread per target) then bypassing
the LIO workqueue can increase performance 20-30%.
