copy_file_range(2): add recommendation to use large "len"
PR#252358 reported a serious performance problem w.r.t. cp(1) when copying large non-sparse files. This problem appears to have been caused by cp(1) calling copy_file_range(2) with a small "len" argument. This patch adds a recommendation to use a large "len" value where possible, for performance reasons. Reviewed by: asomers Differential Revision: https://reviews.freebsd.org/D27935
