From 69f032c92cf883ea74a4b69ba3d91317aa6f174e Mon Sep 17 00:00:00 2001 From: Thomas Gleixner Date: Tue, 5 Nov 2024 09:14:49 +0100 Subject: signal: Provide ignored_posix_timers list To prepare for handling posix timer signals on sigaction(SIG_IGN) properly, add a list to task::signal. This list will be used to queue posix timers so their signal can be requeued when SIG_IGN is lifted later.
