Option to ignore oom_score completely

In my case there's a lot of memory-eager applications which sets themselves oom_score_adj=-1000 and therefore I keep getting xfce4-notifyd (with 25M VmRSS) killed first which occasionally gets an oom_score value of 1 instead of the process that actually ate all of my ram and triggered -m limits (but keeps its oom_score at 0).
I don't really know is that a common problem but anyway, in my opinion it'll be good to have an option to decide which process to kill based exclusively on VmRSS value

rfjakob/earlyoom#140

Fix Makefile: add option for non-systemd

(Minor) Increase PID justification to 7 characters

The maximum PID that can be used on 64-bit linux systems is 2^22, can the padding in oom-sort be increased to 7 chars for PID or determined from /proc/sys/kernel/pid_max? Happy to submit a PR.

Enabling low memory warnings cause slowing down killing the victim

subj

execute_the_command

nohang always try to run command instead of send SIGTERM even if execute_the_command = False

Fallback mode

allow_fallback = False
fallback_mem = 1 M
fallback_swap = 1 M
fallback_zram = 90 %

In a critical situation: disable customization, quickly find a victim by oom_score and send SIGKILL.

Sort by VmRSS if the badness of the processes are the same

Use /dev/chromeos-low-mem

ChromiumOS kernel patches include /dev/chromeos-low-mem pseudo-device
https://gitlab.freedesktop.org/seanpaul/dpu-staging/commit/0b992f2dbb044896c3584e10bd5b97cf41e2ec6d
(as far as I understood from the changelog, it was previously named /dev/low-mem)

That file can be used to detect if system is in low memory condition or not.

Maybe it will be interesting to you. I've never used nohang frankly speaking, just wanted to give an idea...

I guess the problem is that

File context can be temporarily modified with the chcon command. If you want to permanantly change the file context you need to use the semanage fcontext command. This will modify the SELinux labeling database. You will need to use restorecon to apply the labels.

Improvement: show list of worst processes instead of background kill

For me as casual user, is more conveniently to choose process which should be killed. It is difficult to constantly update the priorities of processes in the config, especially since various situations may arise that will be decided not in favor of the user.
I think it's better to show list of worst processes and possibility to pass SIGTERM, SIGKILL to one or many of them. If the indicator of the load on the subsystem reaches critical values, then the process is automatically killed, as it works now.

Badness bug

incorrect badness value in log, will be fixed later

Improve CLI flags parsing

~# nohang -v hh                                                                                                                                                                       
Unknown option: -v

Not sure if this should require extra config-options (enable_cmdline, prefer_cmdline_regex,...) are just be included in the standard behaviour.
