Hi, it's first time for me to report user-space breakage in here, so
i'm begging your pardon.
I want to report that Linux 5.4 breaking my USB mount workflow due
udevadm monitor report here (I'm using vanilla kernel 5.4.39 on
Slackware64 Current and vanilla kernel 4.4.221 on Slackware64 14.2):
$ udevadm monitor
monitor will print the received events for:
UDEV - the event which udev sends out after rule processing
KERNEL - the kernel uevent

Where's udev involvement? In Linux 4.4.221 (Slackware64 14.2), I got
udev involvement in udevadm monitor. When digging to use strace,
here’s comparasion of linux-4.4.221 and linux-5.4.39:

Sorry, but what actually changed that you can see in the logs?
What functionality broke? What used to work that no longer does work?
And 4.4.221 is quite different from 5.4, is that the jump that you are
seeing breakage in, or is it in some smaller jump?
thanks,

I don't understand, what functionality changed? What exactly used to
work that no longer does?
Did you change anything else other than the kernel on your system? Did
you change to a newer version of udev/systemd or anything else?

I'm so sorry for first message mess, because that message has been sent by
Gmail Website. Can I send my logs as attachment? I try to convenient everyone
here. ( FYI, I just switched to Thunderbird with these settings:
https://www.kernel.org/doc/html/v4.12/process/email-clients.html#thunderbird-gui )

linux-5.4 has been never called the udev dependencies whereas
linux-4.4 will call any udev dependencies if necessary, that's the problem.

Sure, attachments work, but better yet, if you can show the difference
in a few lines that is much nicer than having to dig through large
numbers of log files.

I do not understand what exactly you mean by "call udev dependencies".
udev is used to create symlinks and set user/group permissions on device
nodes in /dev/ which is created by devtmpfs. What exactly is not
happening in your /dev/ with the move to a newer kernel?

Have you contacted the eudev developers to see if something different
needs to be set in your kernel when moving 4 years in kernel development
forward? Are you sure you have all the correct config options enabled?
Why such a huge leap forward all at once, how about going from 4.4.y to
4.9.y and then 4.14.y and then 5.4.y? That might help narrow things
down a bit easier.

It's my bad not to contact the eudev developers first. However I'm not quite
sure to contact the eudev developers would solve the problem, but CMIIW.

Unfortunately I need to think twice due almost ran out of electricity

But if these steps are necessary, I'll think solution later.

Again, I really do not understand what exactly is "not working".
Please explain that when you send the new log messages.

Okay, here's compilation of "dmesg | grep -i udev && udevadm
monitor && lsblk" on linux-4.4.221 vs linux-5.4.39. You can check
my attachment here because I can't explain it by words (I'm not
english native speaker anyway, which makes it so difficult to
explain it for me).

It's a weak machine, it took appropriately 2 hours to just compiling
linux kernel. I need to think twice too because electricity is expensive here.
