We can shrink it to exactly 64 bytes (1 cache line on AMD64) Instead of copying a whole struct clocksource, we copy only needed fields. I deleted an unused field : offset_base This patch fixes one oddity in vgettimeofday(): It can returns a timeval with tv_usec = 1000000. Maybe not a bug, but why not doing the right thing ?
