X-Git-Tag: v6.6.7~3906^2~11 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=64c80dfd04d1dd2ecf550542c8f3f41b54b20207;p=platform%2Fkernel%2Flinux-starfive.git xfs: Print XFS UUID on mount and umount events. As of now only device names are printed out over __xfs_printk(). The device names are not persistent across reboots which in case of searching for origin of corruption brings another task to properly identify the devices. This patch add XFS UUID upon every mount/umount event which will make the identification much easier.
