PFS from INODZ

With the level of confusion and cluelessness we had in the beginning of the project, we never expected the project would pick up such a pace. Guess thats how it is when it comes to linux kernel hacking. Unbelievably interesting work to do. Anyway... coming to the progress of the project, We are still working on the pools. We are done with lets say 85-90% of it. There were features and bugs which took much longer than we expected. Since the last blog update, we added these features successfully:
-Adding block devices to pools
-Removing block devices from pools
-Creating pools via IOCTL commands
-Multiple number of pools
-Names to pools

Adding and removing were pretty straight forward. We were stuck when we needed to write a code to return a block_device when the name of the device was given. We finally used this function called open_by_devnum(). Later when our job with the block_devices is over(exiting the module, deleting disks from pool, etc), we use the function blkdev_put() to close the devices.
Then, for creating pools, we decided to have an initial pool called /dev/pool which would recieve and execute all requests(IOCTL) to create pools.

TO-DO list:
-Writing metadata having information about all pools and constituent block devices to pools.
-Scanning all disks at startup to create pools.
-Minor work such as renaming and deleting pools.
-IOCTL commands to list all pools and their member block devices.

Now with that, would complete the work on the pools. Hopefully in another week. We'll probably put the code for the pool on the blog after that.
Then we have to work on the filesystem. A lot of study has to be done. We have no clear direction yet. We expect to get stuck for a long time. As he said... GOD HELP US WITH THAT.
