Hey Stephen

Question for you about a possible -next process change.

Would it be reasonable to have some mechanism to script
treewide patches to generate and apply after Andrew Morton's
mmotm patches are applied to -next?

This could allow treewide scripted patches to have
compilation and test coverage before possibly being
applied to Linus' tree.

What would be necessary to allow this?
