[Bug 1465322] Re: regression: "df: `/sys/kernel/debug': Function not implemented" with 3.2.0-85.122
I can confirm that reverting df438afe2d93 ("debugfs: leave freeing a
symlink body until inode eviction") fixes the issue on an i386 VM. But
it would be great to have the original bug reporter to test that too.

This is confirmed in an amd64 VM and on an amd64 system. It doesn't
make a difference if I use sudo.
