[sshfs] O_TMPFILE on sshfs?

[Sverd J. <sve...@go...>]

A program I use tries this on sshfs and fails:

open("/tmp/2001/remotefs/incoming",
O_WRONLY|O_DIRECTORY|O_CLOEXEC|O_TMPFILE) = -1 EOPNOTSUPP (Operation
not supported)

On non-sshfs it does this:

[...]
open("/tmp/2001/test/incoming", O_WRONLY|O_DIRECTORY|O_CLOEXEC|O_TMPFILE) = 4
[...]
sendfile(4, 3, [0], 95476)              = 95476
[...]
linkat(AT_FDCWD, "/proc/self/fd/4", AT_FDCWD,
"/tmp/2001/test/incoming/foobar", AT_SYMLINK_FOLLOW) = 0
[...]

So I guess O_TMPFILE is not supported at this point?
