(Andrew, perhaps this could bake in -mm for a cycle or two if
there are no objections?)
These patches 1-7 add the Optimized MPEG Filesystem, a proprietary
filesystem used by the embedded devices Rio Karma and ReplayTV
which are no longer manufactured.
I've been maintaining this reverse-engineered filesystem
out-of-tree since around 2.6.12. It has stabilized to the point
that, while not quite feature-complete, it is close enough that
I'm pretty much just applying VFS API updates to it these days.
So, in the spirit of stable_api_nonsense, I request that it be
considered for inclusion for .26 or later.
There is a small user community (<20?) using the driver today.
According to google, it has been packaged by others for Debian,
Ubuntu, and Mandriva.
I have also written an implementation in FUSE. However, in
its current unoptimized state, the FUSE version is about half the
speed of the kernel driver. Either way, the kernel version could
use a review given some distros have apparently picked it up.
version 3:
- fixed sparse warnings
- added more sanity checking in list traversals
version 2:
- removed private inode cache
- included GPL v2 notice
- rewrote omfs_count_free to use hamming weight library functions
- removed duplicated crc-itu-t
Version 1: initial post
