CONFIG_PREEMPT_RT=y possible in Dom0 kernel?
HI,
Is it possible to specify CONFIG_PREEMPT_RT=y in the Dom0 kernel? It seems
that it is forbidden as it is not a menu option in make menuconfig and gets
removed if I manually add it to the .config.
I want to run a sound server on Dom0 and am having problems with xruns at
present, so need to be able to run a preemptive kernel.
Thanks,
Chris...

Following up to the discussion in:
https://lore.kernel.org/r/20200914204209.256266093 at linutronix.de
and the second version of this:
https://lore.kernel.org/r/20201029221806.189523375 at linutronix.de
this series provides a preemptible variant of kmap_atomic & related
interfaces.
This is achieved by:
- Removing the RT dependency from migrate_disable/enable()
- Consolidating all

[PATCH -v2 0/3] jbd2 scalability patches
This version fixes three bugs in the 2nd patch of this series that
caused kernel BUG when the system was under race. We weren't accounting
with t_oustanding_credits correctly, and there were race conditions
caused by the fact the I had overlooked the fact that
__jbd2_log_wait_for_space() and jbd2_get_transaction() requires
j_state_lock to be write locked.
