Subject: btrfs-progs: fix typecast when printing csum value
X-Git-Tag: upstream/4.16.1~3303
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=5e82da1118203d5ab92de3efccc1904b9e24766f;p=platform%2Fupstream%2Fbtrfs-progs.git

btrfs-progs: fix typecast when printing csum value

Only the first byte of the wanted csum is printed:

checksum verify failed on 65536 found DA97CF61 wanted 6B
checksum verify failed on 65536 found DA97CF61 wanted 6BC3870D

Also add leading zeros to the format.
