Do you have any references to specific bugs here? We depend pretty heavily on containers and I'd love to look into these and see if we are impacted and whether we should carry these patches
Set to land in v6.4: https://lore.kernel.org/linux-mm/20230330191801.1967435-1-yo...
To see if you are affected run ‘sudo perf top’ and see if ‘blkcg_rstat_flush()’ shows up.
blkcg_rstat_flush is quite slow on some kernels and it disables IRQs on the cpu which blocks nic queues on the same CPU.
