Since there is no maintainer for the NTFS driver I am sending this
directly to you, Linus, as well as to the LKML.
This pathc fixes the compilation issue with NTFS write support, which
appeared somewhere along 2.3.x, I can't remember and I kept fixing it for
myself so I thought it might be a good idea to post this now that other
people are trying to use it as well).
Be warned: write support is VERY DANGEROUS as it is! - Keep a backup or
you _will_ get bitten (even if it is just by Murphy's Law...). - You have
been warned!
Also you will notice that I inserted myself in the MAINTAINERS file under
a new "NTFS FILESYSTEM" section with Status: Odd Fixes. - Since nobody
else seems to want to do it I will take it up unless you disagree, but I
have extremely limited spare time (don't we all...) so I can't do any more
than "Odd Fixes" at present. - If anyone with more time wants to take over
please feel free to do so... - In the meantime I will do my best to keep
the driver in a state where it at least compiles and if time allows
where it works, too.
The current status (according to my personal testing) is that read-only
works without any problems while write support works except for deleting
files, which doesn't work at all (files don't get deleted).
Regards,
Anton
