Re: [PATCH V7 2/8] posix clocks: introduce a syscall for clock tuning.

On Thursday 16 December 2010, Richard Cochran wrote:

A new syscall is introduced that allows tuning of a POSIX clock. The
syscall is implemented for four architectures: arm, blackfin, powerpc,
and x86.

The new syscall, clock_adjtime, takes two parameters, the clock ID,
and a pointer to a struct timex. Any ADJTIMEX(2) operation may be
requested via this system call, but various POSIX clocks may or may
not support tuning.

The syscall implementation looks good to me.

It would be good to add it to include/asm-generic/unistd.h
as well, so that tile and future architectures get it, too.
