Subject: staging: lustre: ldlm_extent.c: replace IS_PO2 by is_power_of_2
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=5f4179e04b31441b0b7995d14320a457aafba01b;p=openwrt%2Fstaging%2Fblogic.git

staging: lustre: ldlm_extent.c: replace IS_PO2 by is_power_of_2

Replaces IS_PO2 by is_power_of_2. It is more accurate to use
is_power_of_2 since it returns 1 for numbers that are powers
of 2 only whereas IS_PO2 returns 1 for 0 and numbers that are
powers of 2.
