/sys/kernel/address_bits was introduced in #6220 and is not present in older distros according to #6276 .

This should fix it.

Do you know when in which Linux kernel versions /sys/kernel/profiling and /sys/kernel/address_bits were added, and when these versions were released? After all, it wouldn't be a good idea if this lowers the "Minimum Supported Linux Version" only by two months or so, because then #6276 will be re-opened by another person soon afterwards.

Why? I assumed that /sys/kernel/profiling was chosen by Anirban because it is supported by "all" Linux versions?

Yes, the assumption is that /sys/kernel/profiling is supported by almost all linux versions . It should be fine to totally just replace /sys/kernel/address_bits with it.

At the moment I am looking into the changelogs to find out when it was actually added to make sure the assumption actually holds and we don't get a repeat of the same issue few months later.

Hi! The choice of the file looks good, please add a comment so that future readers will immediately know why that file was chosen. (Especially in case there's some other problem and we need to pick yet another file.)

Also, please take the PR out of draft-mode before pushing, so that all checks run.

Did i make a mistake force pushing my formatting commit ? Seems like all of the lints keep failing .

@AnirbanHalder654322 those clippy errors are unrelated to your PR, they fail because there was a new Rust release today. It's addressed in #6330.

LGTM! Let's see whether any CI platform is missing this file, then this can be merged (or more likely: squashed)

Looks like all CI failures are due to other things:

In other words: CI is as green as it can be, given the current circumstances.

TIL: The "Squash and merge" commits generated by Github are ugly as hell. Lesson learned, I'll take more care to edit the message next time.
