Merge tag 'trace-v6.11' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace
Pull tracing updates from Steven Rostedt:
"Trivial updates for 6.11:
- Set rtla/osnoise default threshold to 1us from 5us
The 5us default was missing noise that people cared about. Changing
it to 1us makes it work as expected.
- Restructure how sched_switch prev_comm and next_comm was being saved
The prev_comm was being saved along with the other next fields, and
the next_comm was being saved along with the other prev fields.
This is just a cosmetic change.
- Have the allocation of pid_list use GFP_NOWAIT instead of GFP_KERNEL
The allocation can happen in irq_work context, but luckily, the
size was by default so large, it was never triggered. But in case
it ever is, use the NOWAIT allocation in the interrupt context.
- Fix some kernel doc errors"
