SubjectRe: [patch] cache flush bug in mm/filemap.c (all kernels >= 2.5.30(at least))

I don't think the flush_dcache_page thing is done almost anywhere in the
block/driver level right now.

It isn't and it shouldn't :-)

And we shouldn't be doing io reads to pagecache pages with user
mappings anyway normally. direct-io is a different thing.

We are talking about the case where we are bringing in the
data for the first time, on the page cache lookup miss.
