What do you need that for and how is it different from letting it
use full_name_hash() (which is what it will do if you leave
dentry_operations->d_hash equal to NULL)?

I don't have a specific reason to use msharefs_d_hash(). If full_name_hash() can work, I don't mind reducing amount of code in my patch. I will take a look at it.

Thanks,
Khalid
