Is there something significant in 3.12?

View on HN

It says right there in the post:

* improvements to the dynamic tick code,

* support infrastructure for DRM render nodes,

* TSO sizing and the FQ scheduler in the network layer,

* support for user namespaces in the XFS filesystem,

* multithreaded RAID5 in the MD subsystem,

* offline data deduplication in the Btrfs filesystem, and more.

In case anyone else is curious, DRM in the kernel stands for Direct Rendering Manager [1]. It has nothing to do with the DRM that's usually discussed on HN.

Considering the negative connotations of DRM, I am surprised it isn't named something else.

The name Direct Rendering Manager has been around since the '90s, since the XFree86 days. So I'm pretty sure this abbreviation predates that of the "bad" DRM.

Good to know. Thanks.

All TLA are overloaded.

According to Phoronix benchmarks some workloads benefit greatly from the changes in CPU frequency scaling.

Significant for me, they reverted this bug - https://bugzilla.kernel.org/show_bug.cgi?id=61781

Could not get a dbus connection following resume from suspend. Very annoying.

Progress marches on, but as much as I enjoy some good kernel porn, only one in a thousand HN readers will be affected in any way at all.

Looks like it fixes a bug in eDP clamping that scrambles by screen.

Macbook Air (2013) support works better in 3.12.
