Might be a nice addition, no more patets for MS

nice - added to my TODO list for next release.
would be good if they could push the code to the kernel so no extra maintenance would be needed.

it compiles as a kernel module you need sudo and the kernel files.
I already did all the compiling , how do I added to the kernel?

There is a slackbuild for it also.

the link you posted bases on 'fuse' which works in userspace (much slower) same as 'ntfs3g'. there is no kernel module for it.
samsung developed kernel driver which should be much faster and i would be going with it (once reaches kernel tree).
