Re: patch to allow touch to work on HPFS (and others, maybe??)

So, what it really seems to boil down to is 
for those filesystems that support doing timestamp 
updating via FILE_WRITE_ATTRIBUTES (NTFS systems)
we should use FILE_WRITE_ATTRIBUTES, and for those that
don't (HPFS, etc), they should use GENERIC_WRITE?

Unfortunately, during my brief perusal of MSDN, I didn't see
an easy way to determine the file system type.  

I also see from the message you quoted that ntsec comes 
into play, but I think it still goes back to the filesystem, since
I have ntsec set, and the touch works on my box (using NTFS,
on our PDS shares (also running NTFS, I assume), but not
on my OS2/HPFS box.
