Hello RT Folks! I'm pleased to announce the 4.4.179-rt181 stable release. This release is just an update to the new stable v4.4.179 version and no RT specific changes have been made. You'll notice there is also a v4.4.178-rt180 release available. The stable v4.4.178 update includes bdf3c006b9a2 ("vmstat: make vmstat_updater deferrable again and shut down on idle") which brakes -rt. f01f17d3705b ("mm, vmstat: make quiet_vmstat lighter") fixes this problem; it's part of the -rt1181 release. Furthermore, Greg queued up in the patch and it will be part of the next stable v4.4.y release. You can get this release via the git tree at: git://git.kernel.org/pub/scm/linux/kernel/git/rt/linux-stable-rt.git branch: v4.4-rt Head SHA1: 0da4f74126bb1ff309a97bacd0c7a2fbb8d42553 Or to build 4.4.179-rt181 directly, the following patches should be applied: https://www.kernel.org/pub/linux/kernel/v4.x/linux-4.4.tar.xz https://www.kernel.org/pub/linux/kernel/v4.x/patch-4.4.179.xz https://www.kernel.org/pub/linux/kernel/projects/rt/4.4/patch-4.4.179-rt181.patch.xz Enjoy!
