Subject: rbd: set the 'device' link in sysfs
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=3325322f773bae68b20d8fa0e9e8ebb005271db5;p=linux.git

rbd: set the 'device' link in sysfs

The rbd driver already provides additional information in sysfs
under /sys/bus/rbd, so we should set the 'device' link in the block
device to reference this information.
