Subject: Documentation: sysctl: correct kexec_load_disabled
Date: Wed, 04 Jan 2023 15:38:46 +0100

Patch series "kexec: Add new parameter to limit the access to kexec", v6.

Add two parameter to specify how many times a kexec kernel can be loaded.

These parameter allow hardening the system.

While we are at it, fix a documentation issue and refactor some code.


This patch (of 3):

kexec_load_disabled affects both ``kexec_load`` and ``kexec_file_load``
syscalls. Make it explicit.
