fs: add vfs_iter_{read,write} helpers

2015-01-29T05:13:13Z

Simple helpers that pass an arbitrary iov_iter to filesystems. Signed-off-by: Christoph Hellwig Signed-off-by: Al Viro

new helper: iov_iter_bvec()

2015-01-29T05:13:11Z

similar to iov_iter_kvec(), for ITER_BVEC ones Signed-off-by: Al Viro

2014-10-23T22:14:35Z

Export do_splice_direct() to modules. Needed by overlay filesystem. Signed-off-by: Miklos Szeredi

->splice_write() via ->write_iter()

2014-06-12T04:18:51Z

iter_file_splice_write() - a ->splice_write() instance that gathers the pipe buffers, builds a bio_vec-based iov_iter covering those and feeds it to ->write_iter(). A bunch of simple cases coverted to that... [AV: fixed the braino spotted by Cyrill] Signed-off-by: Al Viro

vfs: fix vmplice_to_user()

2014-05-28T05:54:52Z

Commit 6130f5315ee8 "switch vmsplice_to_user() to copy_page_to_iter()" in v3.15-rc1 broke vmsplice(2). This patch fixes two bugs: - count is not initialized to a proper value, which resulted in no data being copied - if rw_copy_check_uvector() returns negative then the iov might be leaked. Tested OK.

start adding the tag to iov_iter

For now, just use the same thing we pass to ->direct_IO() - it's all iovec-based at the moment. Pass it explicitly to iov_iter_init() and account for kvec vs. iovec in there, by the same kludge NFS ->direct_IO() uses. Signed-off-by: Al Viro

switch vmsplice_to_user() to copy_page_to_iter()

2014-04-02T03:19:23Z

I've switched the sanity checks on iovec to rw_copy_check_uvector(); we might need to do a local analog, if any behaviour differences are not actually bugfixes here... Signed-off-by: Al Viro
