Linux syscall table

Did look several times for a complete and up to date linux syscall table.

Here is a quick hack, to fetch the call numbers and the arguments from the kernel sources, and generate a html table.

The ‘script’ (it is functional, that’s all) is linked below.

Most syscalls are declared within a single file. Few syscalls might not be predeclared at all, and / or to be found within other files. Yet I didn’t need them, and there are the manpages as well.

So, I leave this the way it is.

Looking at this - this won’t win a prize, but, took me only few minutes to setup.

Did look specifically for the landlock syscalls. Which are now numbered below.
