Subject: btrfs-progs: don't overflow colors[] in fragments
X-Git-Tag: upstream/4.16.1~3072
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=29340e68532ede8fef3b0d84c8d4ae0f1b000d26;p=platform%2Fupstream%2Fbtrfs-progs.git

btrfs-progs: don't overflow colors[] in fragments

Stop iteration at the number of elements in the colors[] array when
initializing the elements.  Rather than a magic number.  This was found
by static analysis.
