Thanks for review
And ping
This patch optimizes performance. For example, when executing the following commands in a VM with 180 vCPU:
ip link add dev vm1 type veth peer name vm2 && ip link del vm1,
and then measuring the runtime of tlb_finish_mmu using :
funcslower-bpfcc -t tlb_finish_mmu,
it was observed that the execution time of tlb_finish_mmu called by systemd-udevd has been significantly reduced.
The improvement is attributed to the fact that the" ip link add " command triggers the forking of 260 systemd-udevd processes,
When these processes exit, they need to release memory, which previously caused intense contention on the spinlock.

This patch alleviates that contention, resulting in significantly reduced execution time
