Releasing Linux Kernel 4.5 RC 3, Linus Torvalds said:
“It’s slightly bigger than I’d like, but not excessively so (and not unusually so). Most of the patches are pretty small, although the diff is utterly dominated by the (big) removal a couple of staging rdma drivers that just weren’t going anywhere. Those removal patches are 90% of the bulk of the diff.
Of the remaining 10%, the rest is still mostly drivers (networking, gpu, sound, usb), with the rest being miscellaneous other stuff (core networking, some VM fixes from Andrew, ARM SoC fixes, crypto etc). So it may not be a tiny rc, but there is also nothing particularly worrisome in there.”
