Subject[PATCH 1/2] btrfs-progs: Fix printf format casting errors
From: Alex Chiang <achiang@hp.com>
MIME-Version: 1.0
Content-Type: text/plain; charset=utf-8
Content-Transfer-Encoding: 8bit

We get lots of warnings of the flavor:

utils.c:441: warning: format '%Lu' expects type 'long long unsigned int' but argument 2 has type 'u64'

And thanks to -Werror, the build fails. Clean up these printfs
by properly casting the arg to the format specified.
