Subject: staging: lustre: discard cfs_time_before_64()
X-Git-Tag: v4.19~841^2~696
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=de15ec21bd644a79257079f5d3083fbfcb9655c6;p=platform%2Fkernel%2Flinux-rpi.git

staging: lustre: discard cfs_time_before_64()

cfs_time_before_64 is the same as time_before64()
similarly cfs_time_beforeq_64() matsches time_before_eq64()
So just use the standard interfaces.
