Jan Kara f550ee9b85 iomap: Do not create fake iter in iomap_dio_bio_actor() ... iomap_dio_bio_actor() copies iter to a local variable and then limits it to a file extent we have mapped. When IO is submitted, iomap_dio_bio_actor() advances the original iter while the copied iter is advanced inside bio_iov_iter_get_pages(). This logic is non-obvious especially because both iters still point to same shared structures (such as pipe info) so if iov_iter_advance() changes anything in the shared structure, this scheme breaks. Let's just truncate and reexpand the original iter as needed instead of playing games with copying iters and keeping them in sync. Signed-off-by: Jan Kara <jack@suse.cz> Reviewed-by: Darrick J.
