A bit of background:

Doing only one of the two conversions is a correct patch as well
of course, I just want to make sure you don't have to go through all
the same files again once someone does a blind pushdown into the ioctl
and llseek functions, so once you prove that a specific driver doesn't
need the BKL, please always make sure to remove it from all three places.

I fear that the llseek part will get interesting as well, just because
we call default_llseek instead of no_ll by default currently.
It might be a good idea to add one of .llseek=no_llseek or 
.llseek=generic_file_llseek in any file_operations that you prove
to not require the BKL.
