From 1991299e49fa58c3ba7e91599932f84bf537d592 Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Thu, 8 Jun 2023 13:02:48 +0200 Subject: scsi: replace the fmode_t argument to ->sg_io_fn with a simple bool Instead of passing a fmode_t and only checking it for FMODE_WRITE, pass a bool open_for_write to prepare for callers that won't have the fmode_t.
