Linus has released the 4.4-rc1 prepatch andclosed the merge window for this cycle. "Just looking at the patchitself, things look fairly normal at a high level, possibly a bit moredriver-heavy than usual with about 75% of the patch being drivers, and 10%being architecture updates. The remaining 15% is documentation, filesystem,core networking (as opposed to network drivers), tooling and some coreinfrastructure."
