[PATCH 0/10] use safer test on the result of find_first_zero_bit

From: Julia Lawall
Date: Wed Jun 04 2014 - 05:10:13 EST


Find_first_zero_bit considers BITS_PER_LONG bits at a time, and thus may
return a larger number than the maximum position argument if that position
is not a multiple of BITS_PER_LONG.
