new helper: dup_iter()

2015-02-18T03:21:11+00:00

Copy iter and kmemdup the underlying array for the copy. Returns a pointer to result of kmemdup() to be kfree()'d later. Signed-off-by: Al Viro

new helper: iov_iter_bvec()

2015-01-29T05:13:11+00:00

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

copy_from_iter_nocache()

2014-12-09T01:25:23+00:00

BTW, do we want memcpy_nocache()? Signed-off-by: Al Viro

new helper: iov_iter_kvec()

2014-12-09T01:25:23+00:00

initialization of kvec-backed iov_iter Signed-off-by: Al Viro

iov_iter.c: get rid of bvec_copy_page_{to,from}_iter()

2014-11-27T23:44:13+00:00

Just have copy_page_{to,from}_iter() fall back to kmap_atomic + copy_{to,from}_iter() + kunmap_atomic() in ITER_BVEC case. As the matter of fact, that's what we want to do for any iov_iter kind that isn't blocking - e.g. ITER_KVEC will also go that way once we recognize it on iov_iter.c primitives level Signed-off-by: Al Viro
