The patch provides complete backwards compatibility if _ASSUME_POSIX_TIMERS is not set.
If _ASSUME_POSIX_TIMERS is set then the patch assumes that this also indicates that the cpu timers are available. Which would break binary compatibility. Is that what you are referring to?
Also it seems the patch does not address clock_getcpuclockid() etc. I can add that.
I had to take the material from sysdeps/unix/clock_* and put it into sysdeps/unix/sysv/linux/clock_* because otherwise I would have broken all the other users of sysdeps/unix/clock_*. I need the fallback to the timer syscalls for clockids unknown to glibc that would have meant a significant change to the code in sysdeps/unix/clock_*
I would be very grateful if you could indicate to me what fixes are necessary to make the patch acceptable. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
