From 760ad335d600b1d45f05bc5fad59c05d909710be Mon Sep 17 00:00:00 2001 From: Thomas Gleixner Date: Fri, 11 Sep 2026 11:09:35 +0200 Subject: [PATCH] posix-cpu-timers: Use PF_EXITING to indicate exit Right now POSIX CPU timers use task::exit_state to check whether a task is exiting. That works correctly, but exit_state is set later in do_exit() and too late for allowing to cleanup POSIX timers earlier. It does not matter in case of exit whether the cutoff is a bit earlier.
