[lustre-devel] [RESEND PATCH v2 4/5] staging: lustre: selftest.h: replace IS_PO2 by is_power_of_2

[Aya Mahfouz]

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.
