Subject: btrfs-progs: Fix over-sized limit on buffer
X-Git-Tag: v0.20-rc1~109
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=dfa328ac4e3e077a8972c171715cb64976e8d0f3;p=platform%2Fupstream%2Fbtrfs-progs.git

btrfs-progs: Fix over-sized limit on buffer

gcc-4.4 complains (rightly) that the strncpy has a limit too large for
the array it's copying into. Use the correct array length.
