Why some struct's in the Linuxulator need translation and others don't?

[rbranco]

I'm experimenting with the Linuxulator and found that some structs are defined as `struct l_foo` and others lack the `l_` prefix in syscalls.master:

freebsd-src/sys/amd64/linux/syscalls.master at main · freebsd/freebsd-src

The FreeBSD src tree publish-only repository. Experimenting with 'simple' pull requests.... - freebsd/freebsd-src

github.com

For example, there's `struct iovec` and `struct l_rlimit`. In the latter case it's also weird that some syscalls use`struct rlimit` instead.

I couldn't find a better title for this thread.
