Hello zfs-discuss,

http://git.kernel.org/?p=linux/kernel/git/mason/btrfs-unstable-standalone.git;a=commit;h=eecfe5255c533fefd38072a04e4afb56c40d9719
"If compression for a given set of pages fails to make them smaller, the
file is flagged to avoid future compression attempts later."

Maybe that's a good one - so if couple of blocks do not compress then
flag it in file metadata and do not try to compress any blocks within
the file anymore. Of course for some files it will be suboptimal so
maybe a dataset option?
