+Subject: [PATCH] [SCSI] megaraid_sas: remove sysfs poll_mode_io world writeable permissions
+
+/sys/bus/pci/drivers/megaraid_sas/poll_mode_io defaults to being
+world-writable, which seems bad (letting any user affect kernel driver
+behavior).
+
+This turns off group and user write permissions, so that on typical
+production systems only root can write to it.
