Subject: md: stop defining MAJOR_NR
X-Git-Tag: firefly_0821_release~14816^2~47
X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=3dbd8c2e3ff0185585e068f190289d2a267a3e83;p=firefly-linux-kernel-4.4.55.git

md: stop defining MAJOR_NR

MAJOR_NR was only required for magic in linux/blk.h in 2.4 or earlier
kernels, so no need to keep it around.
