File udev-rules-don-t-generate-multiple-vpdupdate-events-.patch of Package libvpd2.14181
From 3ec780310cca88698fccbf4fb0de20d822ecf88e Mon Sep 17 00:00:00 2001 From: Martin Wilck <mwilck@suse.com> Date: Tue, 28 Jan 2020 16:07:43 +0100 Subject: [PATCH 3/3] udev rules: don't generate multiple vpdupdate events for SCSI/NVMe lsvpd lists SCSI devices, not partitions or block devices. Currently, addition of e.g. /dev/sda will generate events for a "scsi_device", "scsi_disk", "bsg", and "block" device, plus events for partitions, and every event will trigger a "touch /run/run.vpdupdate" command, where touching the file once would be obviously sufficient. Add rules that touch vpdupdate for SCSI hosts and devices, but not for the additional sysfs nodes. Similar reasoning for NVMe. --- 90-vpdupdate.rules | 12 ++++++++++++ 1 file changed, 12 insertions(+) Index: libvpd-2.2.6/90-vpdupdate.rules =================================================================== --- libvpd-2.2.6.orig/90-vpdupdate.rules +++ libvpd-2.2.6/90-vpdupdate.rules @@ -1,3 +1,4 @@ +DEVPATH!="/devices/*", GOTO="vpd_end" # See SysFSTreeCollector::filterDevicePath() DEVPATH=="/devices/virtual/*", GOTO="vpd_end" DEVPATH=="/devices/system/*", GOTO="vpd_end" @@ -18,6 +19,18 @@ DEVPATH=="/devices/uprobe/*", GOTO="vpd_ DEVPATH=="/devices/kprobe/*", GOTO="vpd_end" DEVPATH=="/devices/rbd/*", GOTO="vpd_end" +SUBSYSTEM=="scsi_device", GOTO="vpd_update" +SUBSYSTEM=="scsi_host", GOTO="vpd_update" +# Don't generate extra events, we have one for the scsi_device already +# This rule also skips SCSI block device uevents +# (but the corresponding scsi_device will have triggered vpdupdate). +SUBSYSTEMS=="scsi*", GOTO="vpd_end" + +# virtual NVMe devices (NVMeoF) are skipped because of the rule above +SUBSYSTEM=="nvme", GOTO="vpd_update" +SUBSYSTEM=="nvme-subsystem", GOTO="vpd_update" +SUBSYSTEMS=="nvme*", GOTO="vpd_end" + LABEL="vpd_update" RUN+="/bin/touch /run/run.vpdupdate" LABEL="vpd_end"
