Hi Ted,

Using Linus' tree, today's linux-next build (powerpc ppc64_defconfig)
produced this warning:

fs/ext4/super.c: In function 'parse_options':
fs/ext4/super.c:1600:23: warning: unused variable 'sbi' [-Wunused-variable]

Introduced by commit 26092bf52478 ("ext4: use a table-driven handler for
mount options").  This build has CONFIG_QUOTA not set.
