OK, some patches in the series add buggy code which is then fixed by follow-up patches, but none of the bugs fixed are severe regressions on common configs (e.g. compiler warnings, lockdep/rt errors, or bugs in new drivers). So I thought it's more important to preserve the credit for the fixes. I had to pull 5 patches from git://git.kernel.org/pub/scm/linux/kernel/git/mellanox/linux mlx5-next to get the mlx5 things to work, this seems to be how mellanox guys are always managing things, and they told me they are ok with it.
