[$] Automatic mTHP creation in 7.2
The Linux kernel has long tried to use huge pages as a way to improve
performance, sometimes with more success than others. The size of huge
pages has traditionally been imposed by the hardware, which typically only
offers a couple of relatively large options. In more recent times, though,
the use of multi-size transparent huge pages (mTHPs), with more flexible
sizing implemented in software, has been growing. If all goes well, the
7.2 development cycle will include the addition of [a new feature](h … ⌘ Read more

The 7.0 kernel has been released
Linus has released the 7.0 kernel after a
busy nine-week development cycle.

The last week of the release continued the same “lots of small
fixes” trend, but it all really does seem pretty benign, so I’ve
tagged the final 7.0 and pushed it out.

I suspect it’s a lot of AI tool use that will keep finding corner
cases for us for a while, so this may be the “new normal” at least
for a while. Only time will tell.
