Are you using set_page_dirty to dirty the pages?
Since part of our fs resembles nfs, we use
__set_page_dirty_nobuffers() for
address_space_operations->set_page_dirty, the same way nfs works.
Are you sure you don't have a refcount leak?
One of my partners have already checked the page flags and reference
count. They seem to be all right.
Maybe we should check them again.
Which kernel version do you use?
Have you tried to change vm.lowmem_reserve_ratio? Check
Documentation/sysctl/vm.txt for how to use it.

Tao
