https://github.com/koverstreet/bcache-tools/pull/1 Add bcache-export-cached helper to export CACHED_UUID and CACHED_LABEL always Linux kernel bcache driver does not always emit a uevent[1] for when a backing device is bound to a bcacheN device. When this happens, the udev rule for creating /dev/bcache/by-uuid or /dev/bcache/by-label symlinks does not fire and removes any persistent symlink to a specific backing device since the bcache minor numbers (bcache0, 1, 2) are not guaranteed across reboots. This script reads the superblock of the bcache device slaves,ensuring the slave is a backing device via sb.version check, extracts the dev.uuid and dev.label values and exports them to udev for triggering the symlink rules in the existing rules file. 1. https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1729145 Signed-off-by: Shaoxiong Li <dahefanteng@gmail.com> Signed-off-by: Coly Li <colyli@suse.de> Signed-off-by: cheliequan <cheliequan@inspur.com> (cherry picked from commit 84558fec5f0e4ae5f38ac34dde1775d4eeb766e2)
