From e6a2d72c10405b30ddba5af2e44a9d3d925a56d3 Mon Sep 17 00:00:00 2001 From: Juri Lelli Date: Wed, 7 Nov 2018 12:10:32 +0100 Subject: [PATCH] posix-cpu-timers: Remove useless call to check_dl_overrun() check_dl_overrun() is used to send a SIGXCPU to users that asked to be informed when a SCHED_DEADLINE runtime overruns occur. The function is called by check_thread_timers() already, so the call in check_process_timers() is redundant/wrong (even though harmless). Remove it.
