The following patch is against Josef's btrfs-next repository,
and depends on Arnd Hannemann's patch:
"Btrfs: allow mount -o remount,compress=no"
The method was based on a previous example of checking for
lzo INCOMPAT used by Li Zefan when defragmenting with explicit
compression ("btrfs: Allow to specify compress method when defrag")
in ioctl.c.
Based on feedback on IRC, the two patch version presented in the
previous version has been consolidated into a single patch, and
the helper function was converted to a static inline function.
