FreeBSD support

[anacrolix]

It looks like FreeBSD support won't be possible (in the way I would like) until either open file description locks, or clonefile are implemented. There are notes in the code about the state of those, it looks like clonefile might arrive in the next version of BSD if the interface in ZFS settles down.

FreeBSD 14 is supported now, but probably won't perform as well as other platforms.

Please, explain, which way range locking is broken on FreeBSD?
Documentation on fcntl says it can do F_SETLK/F_SETLKW.

https://man.freebsd.org/cgi/man.cgi?query=fcntl&sektion=2&n=1

Or you use some other kind of range blocking?

[anacrolix]

Thanks for the question, I'll check what the state is again.

Perhaps you mean “mandatory” locks, not “advisory”?

And I see that “fcntl F_SETLCK” is per-process lock, not per file descriptor.

What do you use on Linux+Ext4? I can't easily navigate through your code, sorry.
