So like this...  (BTW what's up with my other pending xfstests
patches?  Would you like me to resend a whole back with the
reviewed-by lines merged in?)

Subject: [PATCH] defrag: require falloc support for ext4 defrag

system configurations which don't enable extents do not support
fallocate, so we should skip the defrag tests in that case.
