If anyone wants a look NTFS TNG already has gone all the way (for a while
now in fact). Both fs inode and super block are fs internal slab caches and
both use static inline NTFS_I / NTFS_SB functions and the ntfs includes
from linux/fs.h are removed altogether. Code is in sourceforge cvs. For
instructions how to download the code or to browse it online, see:
http://sourceforge.net/cvs/?group_id=13956
The module of interest is ntfs-driver-tng.
If anyone is doing patches for all kernel file systems, don't bother with
ntfs in 2.5 as NTFS TNG will replace the old ntfs driver soon (certainly in
2.5 time frame).
