Thank you for your reply Jiri, but I believe you're referring to
commits that are in stable kernels and that are not on Linus tree.  I
do understand that these are required occasionally for the reasons you
stated above, and they are usually provided by subsystem maintainers.

However, the initial discussion was about commits that are not in a
public release (e.g. a Linus rc kernel) at kernel.org.

Cheers,
