Subject: [RFC PATCH 0/8] use core page calls instead of kmaps

This RFC is based on the discussion going on the linux-fsdevel [1].

I've tested this on the brd and null_blk. The fio verify job seems to
run without any error on the top of the original series applied [1].

Any feedback is welcome to move this forward.
