From: Rutuja Shah <rutu.shah...@gmail.com>
Hi,
This patch replaces get_ticks_per_sec() calls to NANOSECONDS_PER_SECOND. Also,
as there are no callers, get_ticks_per_sec() has been removed. Replacement
imporves readability and understandability of code.
Example given by Paolo Bonzini,
timer_mod(fdctrl->result_timer,
qemu_clock_get_ns(QEMU_CLOCK_VIRTUAL) + (get_ticks_per_sec() / 50));
NANOSECONDS_PER_SECOND makes it obvious that the timer will expire in 1/50th of
a second.
