--- Comment #3 from Elvis Stansvik (elvstone@gmail.com) ---

I'm hit by this on 4.10 a well (the default kernel on Ubuntu 16.04).

I attached a full test case showing.

Example run:

[estan@newton renameat2tc]$ gcc renameat2.c 
[estan@newton renameat2tc]$ touch foo
[estan@newton renameat2tc]$ ./a.out foo bar
Invalid argument
[estan@newton renameat2tc]$ uname -a
Linux newton 4.10.0-37-generic #41~16.04.1-Ubuntu SMP Fri Oct 6 22:42:59 UTC
2017 x86_64 x86_64 x86_64 GNU/Linux
[estan@newton renameat2tc]$ mount | grep " / "
/dev/sda1 on / type ext4 (rw,noatime,discard,errors=remount-ro,data=ordered)

The reason I discovered it was that Qt recently started using this syscall,
which in turn made Qt Creator (a Qt application) fail to write its config
files.
