% mkdir testit
% cd testit
% mkdir x x/z y z z/a
% mv x/z .
mv: rename x/z to ./z: Directory not empty
% mv x/z y
mv: rename x/z to y/z: Invalid argument
The first error (not empty) is correct but the second is not.
The directory y has just been created and is empty, so there is
no reason for the rename to fail. Attempting to rename x/z to
x/zz also fails. Previously, leaving it alone for a while seemed
to "fix" it but I can't repeat that now (impatience?).
I know little about the kernel level but could it be that the
inode for x/z is not unlocked after the original error?
It makes no difference whether the filesystem is level 0 or level 2.
