Already did..should've included it. It's not particularly revealing to
me though (I've attached the trace). The syscall goes as:
renameat2(AT_FDCWD, "/home/john/mnt/sshfs/status-20180806", AT_FDCWD,
"/home/john/mnt/sshfs/status-20180807", RENAME_NOREPLACE) = -1 ERANGE
(Numerical result out of range)
Also, I've run some a quick 'n dirty code to simply do the rename
syscall which gives the same result.
But, if in this code I simply invoke glibc's renameat() (which is
renameat2() less the "flags" arg), I do not get any errors. So perhaps
the issue is related to the RENAME_NOREPLACE flag. In fact, with my test
code, if I do the syscall renameat2 with flags = 0, then also no error.
Note that in my test cases the source and destinations are regular files
and the destination does not exist. If the destination does exist, then
I get a different error:
mv ~/mnt/sshfs/status-20180806 ~/mnt/sshfs/status-20180807
error: 17 File exists
which, of course, does not occur for "local" files.

Sure, run this:
strace mv ~/mnt/sshfs/status-2018080{6,7}
and look at the strace output.
