Background of Linux's "file-max" and "nr_open" limits on file descriptors (2021)

[pixl97]

>Specifically on Linux there are two system-wide sysctls: fs.nr_open and fs.file-max. (Don't ask me why one uses a dash and the other an underscore, or why there are two of them...)

Somewhere it should be lore that the person that named these syscalls went on to name functions in PHP.

The creat(3) tradition lives on.

What doe NR stand for ?

[foresto]

I've seen it used for (the local equivalent of) "number" in various countries.

Probably NumbeR.

Seems to be “normal resources”, where normal probably meant file descriptor based.
