Yan, Zheng f00a344718 ceph: only dirty ITER_IOVEC pages for direct read ... commit 85784f9395 upstream. If a page is already locked, attempting to dirty it leads to a deadlock in lock_page(). This is what currently happens to ITER_BVEC pages when a dio-enabled loop device is backed by ceph: $ losetup --direct-io /dev/loop0 /mnt/cephfs/img $ xfs_io -c 'pread 0 4k' /dev/loop0 Follow other file systems and only dirty ITER_IOVEC pages.
