6.8-stable review patch. If anyone has any objections, please let me know.
------------------
From: John Stultz <jstultz@xxxxxxxxxx>
commit ed366de8ec89d4f960d66c85fc37d9de22f7bf6d upstream.
Building with clang results in the following warning:
posix_timers.c:69:6: warning: absolute value function 'abs' given an
argument of type 'long long' but has parameter of type 'int' which may
cause truncation of value [-Wabsolute-value]
if (abs(diff - DELAY * USECS_PER_SEC) > USECS_PER_SEC / 2) {
^
So switch to using llabs() instead.
Fixes: 0bc4b0cf1570 ("selftests: add basic posix timers selftests")
