One week after the [1]Linux 6.15 merge window was capped off, the Linux 6.15-rc2 release is now available in rolling up all of the early fixes that were collected over the past week.

Among the fixes merged this week for Linux 6.15-rc2 include some [2]Spectre RSB mitigation clean-ups for AMD/Intel processors and [3]various graphics driver fixes including for a flickering issue on the Intel side while the AMDGPU driver squeezed in the device memory "DMEM" cgroups support. There was also a wide assortment of other random fixes throughout the codebase from the early Linux 6.15 kernel testing.

Linus Torvalds wrote in the [4]6.15-rc2 announcement :

"Things look fairly normal. Yes, this was a larger-than-usual merge indow, but at least for now rc2 looks pretty much in line with normal statistics both when it comes to number of commits and to the diffstat. Nothing particularly stands out to me, but it's early in the release yet, so let's see how it goes...

About a quarter of the patch is selftests updates, which is perhaps a bit unusual but at the same time certainly not alarming.

Other than that, it's all pretty evenly spread out: drivers (gpu is about half of that), arch updates, core kernel and networking, filesystems, documentation. A little something for everybody, in other words."
