Specific to Linux AT_NO_AUTOMOUNT flag tells the kernel to not automount the
terminal component of pathname if it is a directory that is an automount point.
As it is the default for FreeBSD silencly ignore this flag.
glibc-2.34 uses this flag in the stat64 system calls which is used by i386.

linux(4): Implement name_to_handle_at(), open_by_handle_at()2020-11-17T19:51:47ZConrad Meyercem@FreeBSD.org2020-11-17T19:51:47Zurn:sha1:de774e422e7f8abf9d4c6084165c9de66f11b2de
They are similar to our getfhat(2) and fhopen(2) syscalls.

linuxolator: implement memfd_create syscall2020-06-29T03:09:14ZKyle Evanskevans@FreeBSD.org2020-06-29T03:09:14Zurn:sha1:5403f186a7634f49ebe710441ce609445dcc9592
This effectively mirrors our libc implementation, but with minor fudging --
name needs to be copied in from userspace, so we just copy it straight into
stack-allocated memfd_name into the correct position rather than allocating
memory that needs to be cleaned up.
The sealing-related fcntl(2) commands, F_GET_SEALS and F_ADD_SEALS, have
also been implemented now that we support them.
Note that this implementation is still not quite at feature parity w.r.t.
the actual Linux version; some caveats, from my foggy memory:
- Need to implement SHM_GROW_ON_WRITE, default for memfd (in progress)
- LTP wants the memfd name exposed to fdescfs
- Linux allows open() of an fdescfs fd with O_TRUNC to truncate after dup.
(?)
Interested parties can install and run LTP from ports (devel/linux-ltp) to
confirm any fixes.

linux_renameat2: improve flag checks2019-11-07T15:51:44ZEd Masteemaste@FreeBSD.org2019-11-07T15:51:44Zurn:sha1:01b9ee4c509e2882147af35eea4772d06ecd4150
In the cases where Linux returns an error (e.g. passing in an undefined
flag) there's no need for us to emit a message. (The target of this
message is a developer working on the linuxulatorm, not the author of
presumably broken Linux software).
