Re: do_generic_mapping_read performance issue

I would like to submit a patch to fix the performance problem. The
simplest solution is to remove the check. Even in the situation where an
application does not read in PAGE_SIZE multiples as described above, if
the page is accessed frequently it should remain in the cache. However, I
am open to suggestions for a more sophisticated scheme.

Well, yes, that's an obvious solution. I just wanted to make sure that
such change won't break some other load. But so far it seems it won't...

I would like to find out if the change I am suggesting will cause any other problems. Is there someone else I should contact before submitting a patch? Or should I just wait another day or two for comments?
