Some more or less humble suggestions for 2.6:
Documentation/filesystems/ntfs.txt
-- overview says "works only in read-only mode" rather than also
mentioning
the partial rw support available
-- overview needs a reference to the project website,
http://linux-ntfs.sourceforge.net,
with a description of all the material available there, (FAQ, NTFS
on-disk format docs, ...)
-- overview needs to mention ntfsprogs (!)
-- reorder sections: "Features" before "Supported mount options"
-- Section "Limitiations when using the MD driver":
Implement a test in code for the dangerous case that the
documentation warns
for (hoping this is possible ;) and refuse to mount such MDs (or
mount ro?).
-- Add section saying "we" know the NTFS format well enough to have
write support,
if we only would have time or someone would step in to sponsor
(thus magically creating time)
fs/Kconfig
-- CONFIG_NTFS_FS
-- needs direct mention of project website,
http://linux-ntfs.sourceforge.net
-- mention ntfsprogs (!)
-- CONFIG_NTFS_RW
-- described as (DANGEROUS) and:
| This enables the experimental write support in the NTFS driver.
|
| WARNING: Do not use this option unless you are actively developing
| NTFS as it is currently guaranteed to be broken and you
| may lose all your data!
|
| It is strongly recommended and perfectly safe to say N here.
This warning seems outdated ("guaranteed to be broken"?)

The new features compared to the old driver, we collected last time, I list here, http://mlf.linux.rulez.org/mlf/ezaz/ntfsresize.html#write I'd have liked this to be on the Project Status page along with the other updates but the Webmaster didn't answer :) Feel free to copy, etc. Szaka |

Feel free to send me patches for all of the below... If you are doing it please rephrase the DANGEROUS and "guaranteed to be broken" to EXPERIMENTAL and "while we cannot guarentee that it will not damage any data we have so far not received a single report where the driver would have damaged someones data so we assume it is perfectly safe to use". Feel free to rephrase any way you like...

Note: Documentation/ntfs.txt is not updated yet, it's on the todo list for the weekend. I've now checked in changes to bk://linux-ntfs.bkbits.net/ntfs-2.5 for fs/Kconfig. Please have a look and update to your liking. Anton, I'm going away for two days so when/if you're happy with it please ask Linus to pull the new version. I also took the plunge of removing the EXPERIMENTAL bit on the write support. I didn't update the help for the NTFS_DEBUG option. The current help text for NTFS_DEBUG is the original from the NTFS 1.x days. Is that ok with everyone?

"NTFS is the file system of Microsoft Windows NT, 2000 and XP" and Windows Server 2003. It uses the same NTFS as XP. Many people reported driver, ntfsresize success on Windows Server 2003 NTFS. "The only supported operation is overwriting existing files, without changing the file length" The file size must be also over 1 kB for guaranteed permanent changes. "While we cannot guarantee that it will not damage any data, we have so far not received a single report where the driver would have damaged someones data so we assume it is perfectly safe to use." This is humbug. Nobody guarantees. See Microsoft docs when they admit their driver do corrupt NTFS. In certain cases reiserfs collapses, just like ext3 could/can corrupt. Saying "we cannot guarantee" leaves a negative impression in the reader. It could be rephrased something like: "No know problem with this driver, if you find otherwise then please report it to lin...@li..." This is even true. "Topologi-Linux" It's spelled as TopologiLinux, however its url is indeed http://topologi-linux.sourceforge.net > I also took the plunge of removing the EXPERIMENTAL bit on the write > support. Well, it's EXPERIMENTAL something like ... over 1 year without any bug report? Seems reasonable its removal. > I didn't update the help for the NTFS_DEBUG option. The current help > text for NTFS_DEBUG is the original from the NTFS 1.x days. Is that ok > with everyone? I've already recommended once to include NTFS_DEBUG always, just like several other drivers do It was a BIG pain to debug the hangs and IO errors when users can't or don't want to recompile the kernel, aka usually it was impossible.
