The problem with a per_cpu biglock is that you may consume a lot of
RAM for big NR_CPUS. Count 32 KB per 'biglock' if NR_CPUS=1024
Does one Linux kernel run on system with 1024 cpus? I guess it must fry spinlocks... (or even lockup due to spinlock livelocks) Not here in my house, but I was told such beasts exist somewhere on this planet :) You can have a kernel compiled with NR_CPUS=1024, but still run it on your laptop, with a single CPU available... | ||||||||||
