Hello Andreas,
I am wondering if you would be interested too in modifying the VFS layer
to provide non-case-sensitive operations - at least a "casestat"
operation.
This can greatly enhance the performance of Samba when large directories
are present. I have myself added such a "casestat" operation in my Samba
VFS module.
The difficult point then is to take it into account in the Samba code,
e.g. I was able to update filename.c, but I gave up for
call_trans2findfirst().
