Subject: [PATCH 228/266] panic: skip get_random_bytes for RT_FULL in
|
|
init_oops_id
|
|
Origin: https://www.kernel.org/pub/linux/kernel/projects/rt/4.19/older/patches-4.19.31-rt18.tar.xz
|
|
|
|
Disable on -RT. If this is invoked from irq-context we will have problems
|
|
to acquire the sleeping lock.
