[PATCH v1 2/6] iov_iter: optimise bvec iov_iter_advance()

iov_iter_advance() is heavily used, but implemented through generic iteration. As bvecs have a specifically crafted advance() function, i.e. bvec_iter_advance(), which is faster and slimmer, use it instead. Signed-off-by: Pavel Begunkov --- lib/iov_iter.c | 19 +++ 1 file changed
