Subject: [PATCH 1/1] btrfs-progs: fix compiler warning
Date: Tue,  3 Jun 2014 13:37:45 +0200	[thread overview]
Message-ID: <1401795465-27713-1-git-send-email-mail@eworm.de> (raw)

gcc 4.9.0 gives a warning: format ‘%d’ expects argument of type ‘int’,
but argument 2 has type ‘u64’

Using %llu and casting to unsigned long long (same as bytenr) fixes this.
