Hey Guys , I am new to reading and writing kernel code.I got interested in writing code for btrfs as it seems to need more work then other file systems and this seems other then drivers, a good use of time on my part. I interested in helping improving the compression of btrfs by using a set of threads using work queues like XFS or reads and keeping the page cache after reading compressed blocks as these seem to be a great way to improve on compression performance mostly with large partitions of compressed data. I am not asking you to write the code for me but as I am new a little guidance and help would be greatly appreciated as this seems like too much work for just a newbie. Thanks A lot, Nick
