Subject: [PATCH] udev: fix some incorrect usages of CLOCK_BOOTTIME (#6198) | ||
|
||
CLOCK_BOOTTIME should only be used if we actually want the clock to | ||
count on while we are suspended, and it is hence not useful for normal | ||
code execution time limits, fix that. | ||
|
||
Moreover, a couple of uses were even more broken, as | ||
clock_bottime_or_monotonic() was called where actually | ||
now(clock_boottime_or_monotic()) was supposed to be called. Ouch! | ||
|
||
Fixes: #5903 | ||
