Hello, Linus,
Please pull the following CSD-lock change:
git://git.kernel.org/pub/scm/linux/kernel/git/paulmck/linux-rcu.git tags/csd-lock.2023.10.23a # HEAD: 94b3f0b5af2c7af69e3d6e0cdd9b0ea535f22186: smp,csd: Throw an error if a CSD lock is stuck for too long (2023-10-16 16:06:37 -0700)
---------------------------------------------------------------- CSD lock commits for v6.7
This series adds a kernel boot parameter that causes the kernel to panic if one of the call_smp_function() APIs is stalled for more than the specified duration. This is useful in deployments in which a clean panic is preferable to an indefinite stall.
