From 7e63b5a4a68309383868b3582e92c217ad8a5347 Mon Sep 17 00:00:00 2001 From: Douglas Gilbert Date: Sat, 23 Jun 2018 12:22:14 +0200 Subject: [PATCH] scsi: core: scsi_io_completion: comment on end_request return scsi_end_request() is called multiple times from scsi_io_completion() which branches on its bool returned value. Add comment before the static definition of scsi_end_request() about the meaning of that return.
