From f06a44e235ef188689ba23ffc72e9e89b10951a9 Mon Sep 17 00:00:00 2001 From: "Ewan D. Milne" Date: Tue, 15 Sep 2026 13:38:00 -0400 Subject: [PATCH] scsi: devinfo: Add BLIST_SKIP_IO_HINTS for EMC Symmetrix EMC Symmetrix returns an error on MODE SENSE for page 0Ah subpage 05h because it does not implement the SBC-5 I/O hints. These commands began to be sent as a result of commit 4f53138fffc2 ("scsi: sd: Translate data lifetime information"). Add BLIST_SKIP_IO_HINTS to avoid sending these commands because in large configurations the failed commands are displacing other useful information in internal error logs. Signed-off-by: Ewan D.
