Merge branch 'work.iov_iter' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs
Pull iov_iter updates from Al Viro: - bio_{map,copy}_user_iov() series; those are cleanups - fixes from the same pile went into mainline (and stable) in late September. - fs/iomap.c iov_iter-related fixes - new primitive - iov_iter_for_each_range(), which applies a function to kernel-mapped segments of an iov_iter. Usable for kvec and bvec ones, the latter does kmap()/kunmap() around the callback. _Not_ usable for iovec- or pipe-backed iov_iter; the latter is not hard to fix if the need ever appears, the former is by design. Another related primitive will have to wait for the next cycle - it passes page + offset + size instead of pointer + size, and that one will be usable for everything _except_ kvec. Unfortunately, that one didn't get exposure in -next yet, so... - a bit more lustre iov_iter work, including a use case for iov_iter_for_each_range() (checksum calculation) - vhost/scsi leak fix in failure exit - misc cleanups and detritectomy... * 'work.iov_iter' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs: (21 commits) iomap_dio_actor(): fix iov_iter bugs switch ksocknal_lib_recv_...() to use of iov_iter_for_each_range() lustre: switch struct ksock_conn to iov_iter vhost/scsi: switch to iov_iter_get_pages() fix a page leak in vhost_scsi_iov_to_sgl() error recovery new primitive: iov_iter_for_each_range() lnet_return_rx_credits_locked: don't abuse list_entry xen: don't open-code iov_iter_kvec() orangefs: remove detritus from struct orangefs_kiocb_s kill iov_shorten() bio_alloc_map_data(): do bmd->iter setup right there bio_copy_user_iov(): saner bio size calculation bio_map_user_iov(): get rid of copying iov_iter bio_copy_from_iter(): get rid of copying iov_iter move more stuff down into bio_copy_user_iov() blk_rq_map_user_iov(): move iov_iter_advance() down bio_map_user_iov(): get rid of the iov_for_each() bio_map_user_iov(): move alignment check into the main loop don't rely upon subsequent bio_add_pc_page() calls failing ... and with iov_iter_get_pages_alloc() it becomes even simpler ...
