xfs getting case-insensitive filesystem support...

[Dan Kegel]

Hrm.  This is interesting:

I wonder if Wine could run faster if it could delegate
the case-insensitvity to the filesystem...

Would be nice indeed, but I don't think it will come: Linus shot down
similar patches in the past because to_lower may be easy to implement
for ascii, but once you want to implement it for all charsets supported
by the files system it gets very messy.

Sure, it's messy until the filesystem is unicode internally, and uses
something more reasonable instead of a multibyte UTF-8.

Unix filesystems treat filenames as byte-strings, this is 100% reasonable :-)
Any conversion to glygps isn't a filesyatem operation.
