From 73bcb24d932912f8e75e1d88da0fc0ac6d4bce78 Mon Sep 17 00:00:00 2001 From: Rutuja Shah Date: Mon, 21 Mar 2016 21:32:30 +0530 Subject: Replaced get_tick_per_sec() by NANOSECONDS_PER_SECOND This patch replaces get_ticks_per_sec() calls with the macro NANOSECONDS_PER_SECOND. Also, as there are no callers, get_ticks_per_sec() is then removed. This replacement improves the readability and understandability of code. For example, timer_mod(fdctrl->result_timer, qemu_clock_get_ns(QEMU_CLOCK_VIRTUAL) + (get_ticks_per_sec() / 50)); NANOSECONDS_PER_SECOND makes it obvious that qemu_clock_get_ns matches the unit of the expression on the right side of the plus.
