NFS: Fix up the dirty page accounting (3925675c) · Commits · 戴 / test

There is now no reason to account for the dirty pages in the NFS code, since the VM code will now do it for us via __set_page_dirty_nobuffers(), and set_page_writeback(). We still need to keep the accounting of stable writes, though. Signed-off-by:
