Sorry for the mistake of the previous patch. If -1 is passed to the argument pid of clock_getcpuclockid(), the macro MAKE_PROCESS_CPUCLOCK(pid,CPUCLOCK_SCHED) uses it to make the pidclock to 2, and than passes the number 0x2 to the system call clock_getres().
The posix says that if _POSIX_CPUTIME is defined, implementations shall support clock ID values obtained by invoking clock_getcpuclockid(), which represent the CPU-time clock of a given process, implementations shall also support the special clockid_t value CLOCK_PROCESS_CPUTIME_ID, which represents the CPU-time clock of the calling process when invoking one of the clock_*() or timer_*() functions. So passing -1 as the argument pid represents the special CLOCK_PROCESS_CPUTIME_ID. This patch change -1 to -2 as the argument. Make the test to a normal one, but not a special used value. And acctually, the Linux kernel has already supported this special one.
