Subject: fsck.minix: fix "array subscript is above array bounds"
X-Git-Tag: v2.20-rc1~67
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=06c0375ce37cd78cd6e589fbc343a6e1cb240d26;p=thirdparty%2Futil-linux.git

fsck.minix: fix "array subscript is above array bounds"

fsck.minix.c: In function ‘map_block2’:
fsck.minix.c:486:9: warning: array subscript is above array bounds [-Warray-bounds]

The 'blknr' has to be bigger than 7 + 256 + (256 * 256) for i_zone[9].
