From 1f41b6bb83a528a67934c5504094903afff7ab15 Mon Sep 17 00:00:00 2001 From: Hauke Mehrtens Date: Sat, 22 Apr 2023 19:36:22 +0200 Subject: [PATCH] kernel: Activate CONFIG_SCHED_STACK_END_CHECK This activates the CONFIG_SCHED_STACK_END_CHECK option. The kernel will check if the kernel stack overflowed in the schedule() function. This just adds a very small computational overhead. This option is activated in Debian by default.
