Subject: CRC32C big endian bugs...
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=355351fc1dde9bd2c525e40c6228b9db07d95cae;p=platform%2Fupstream%2Fbtrfs-progs.git

CRC32C big endian bugs...

The CRC32C implementation in the btrfs progs is different from the one
in the kernel, so obviously nothing can possibly work on big-endian.
