Re: [PATCH] RTC: Add mmap method to rtc character driver

Yes, but if its in trade for something thats being used currently which hurts more (case in point being the X server), using this solution is a net gain.

...in the short term.

I'm not arguing with you that adding a low res gettimeofday vsyscall is a better long term solution, but doing that requires potentially several implementations in the C library accross a range of architectures, some of which may not be able to provide a time solution any better than what the gettimeofday syscall provides today. The /dev/rtc solution is easy, available right now, and applies

to all arches.

"All"?
