They have no\nessential function for the VM.\n\nWe use a simple increment of per cpu variables. In order to avoid the most\nsevere races we disable preempt. Preempt does not prevent the race between\nan increment and an interrupt handler incrementing the same statistics\ncounter. However, that race is exceedingly rare, we may only loose one\nincrement or so and there is no requirement (at least not in kernel) that\nthe vm event counters have to be accurate.\n\nIn the non preempt case this results in a simple increment for each\ncounter. For many architectures this will be reduced by the compiler to a\nsingle instruction. This single instruction is atomic for i386 and x86_64.\n And therefore even the rare race condition in an interrupt is avoided for\nboth architectures in most cases.\n\nThe patchset also adds an off switch for embedded systems that allows a\nbuilding of linux kernels without these counters.\n\nThe implementation of these counters is through inline code that hopefully\nresults in only a single instruction increment instruction being emitted\n(i386, x86_64) or in the increment being hidden though instruction\nconcurrency (EPIC architectures such as ia64 can get that done).\n\nBenefits:\n- VM event counter operations usually reduce to a single inline instruction\n on i386 and x86_64.\n- No interrupt disable, only preempt disable for the preempt case.\n Preempt disable can also be avoided by moving the counter into a spinlock.\n- Handling is similar to zoned VM counters.\n- Simple and easily extendable.\n- Can be omitted to reduce memory use for embedded use.\n\nReferences:\n\nRFC
