From 8207d645582e96c56950674e104653d0cd552d60 Mon Sep 17 00:00:00 2001 From: Hongxu Jia Date: Fri, 17 Nov 2017 09:46:00 +0800 Subject: [PATCH] rules: watch metadata changes in ide devices Formatting IDE storage does not trigger "change" uevents. As a result clients using udev API don't get any updates afterwards and get outdated information about the device. ... root@qemux86-64:~# mkfs.ext4 -F /dev/hda1 Creating filesystem with 262144 4k blocks and 65536 inodes Filesystem UUID: 98791eb2-2bf3-47ad-b4d8-4cf7e914eee2 root@qemux86-64:~# ls /dev/disk/by-uuid/98791eb2-2bf3-47ad-b4d8-4cf7e914eee2 ls: cannot access '/dev/disk/by-uuid/98791eb2-2bf3-47ad-b4d8-4cf7e914eee2': No such file or directory ... Include hd* in a match for watch option assignment. Upstream-Status: Denied qemu by default emulates IDE and the linux-yocto kernel(s) use CONFIG_IDE instead of the more modern libsata, so disks appear as /dev/hd*. A similar patch rejected by upstream because CONFIG_IDE is deprecated.
