I noticed that in contrast to other kernel core parameters (e.g. kernel.panic, kernel.panic_on_warn, kernel.panic_print) crash_kexec_post_notifiers is not available as a sysctl tunable. I am aware that because it is a kernel core parameter, there is already an entry under: /sys/module/kernel/parameters/crash_kexec_post_notifiers and that allows us to read/modify it at runtime. However, I thought it should also be available via sysctl, since users that want to read/set this value at runtime might look there first. I believe there is an ongoing effort to clean up kernel/sysctl.c, but it wasn't clear to me if this entry (and perhaps the other panic related entries too) should be placed on kernel/panic.c. I wanted to verify first that this change would be welcomed before doing additional refactoring work. I'd appreciate any comments or suggestions.
