Miklos Szeredi 8aa6a2a34f fuse: direct-io: don't dirty ITER_BVEC pages ... commit 8fba54aebbdf1f999738121922e74bf796ad60ee upstream. When reading from a loop device backed by a fuse file it deadlocks on lock_page(). This is because the page is already locked by the read() operation done on the loop device. In this case we don't want to either lock the page or dirty it. So do what fs/direct-io.c does: only dirty the page for ITER_IOVEC vectors.
