open.2: In O_TMPFILE example, describe alternative linkat() call
...
This was already shown in an earlier version of the page,
but Adam Borowski's patch replaced it with an alternative.
Probably, it is better to show both possibilities.

open.2: No need for /proc to make an O_TMPFILE file permanent
...
In the example snippet, we already have the fd, thus there's no
need to refer to the file by name. And, /proc/ might be not
mounted or not accessible.

open.2: Document ENXIO for sockets
...
Linux returns ENXIO when attempting to open() a UNIX domain socket.
Kernel-wise, I believe this happens in fs/inode.c [1], where a constant
`no_open` function returning -ENXIO is registered as the default open()
handler for inodes in inode_init_always(), and is not specialized in
nit_special_inode() as it is for other types.
Seen in the systemd v238 source code [2].

Demo:

[...]
[...]
open("/x", O_WRONLY|O_CREAT|O_TRUNC, 0666) = -1 ETXTBSY (Text file busy)
[...]
[...]
open("/x", O_WRONLY|O_CREAT, 0666) = 3
dup2(3, 1) = 1
close(3) = 0
read(0, "\0\0\0\0[...]"..., 512) = 512
write(1, "\0\0\0\0[...]"..., 512) = 512
[...]
The second one is in kernel_read_file -> deny_write_access.

Looking at <features.h> (or feature_test_macros(7)), one can
see that when _XOPEN_SOURCE is defined with the value 700
(or greater), then _POSIX_C_SOURCE is defined with the value
200809L (or greater). Therefore, terms in the man pages such as
_XOPEN_SOURCE\ >=\ 700 || _POSIX_C_SOURCE\ >=\ 200809L
can be simpified to:
_POSIX_C_SOURCE\ >=\ 200809L

open.2: Remove accidental mention of O_TTY_INIT
...
An earlier edit mentioned O_TTY_INIT as a file creation flag.
That's true, according POSIX, but Linux does not implement
this flag, so remove mention of it.
