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.
