POSIX makes "the CPU-time clock of the calling thread" (i.e., CLOCK_THREAD_CPUTIME_ID) a special case which returns EINVAL instead of ENOTSUP. However, the clock_nanosleep syscall treats this clock just like any other, and returns -EOPNOTSUPP to indicate an unimplemented nanosleep handler. So we need to handle this ourselves in userspace. This change fixes the LTP clock_nanosleep01 testcase. Change-Id: If3bed940d276834bcd114d8c17f96197e9384711 Signed-off-by: Greg Hackmann <ghackmann@google.com>
