Dear RT folks!
I'm pleased to announce the v3.12.0-rt1 patch set.
Changes since v3.10.18-rt14
- updated to v3.12
- dropped SLAB support. It was broken in v3.10 and therefore not available
for RT. Nobody complained except that it did not compile on !RT. Since
SLUB performs a little better compared to SLAB and is the default
allocator I think it is okay to drop SLAB support.
- the PREEMPT_RT Kconfig patches are now very early in the queue.
This is the first release of the v3.12 kernel. It run a couple of days on
powerpc and x86 without an accident :)
Known issues:
- bcache is disabled.
- an ancient race (since we got sleeping spinlocks) where the
TASK_TRACED state is temporary replaced while waiting on a rw
lock and the task can't be traced.
The RT patch against 3.12 can be found here:
https://www.kernel.org/pub/linux/kernel/projects/rt/3.10/...
The split quilt queue is available at:
https://www.kernel.org/pub/linux/kernel/projects/rt/3.10/...
and it will be moved to the usual location once I able to do so.
Sebastian
