$ mount -t overlay overlay -olowerdir=a,upperdir=b,workdir=c z
$ python
>>> fd = open("z/a", "w")
>>>
$ ls -l /proc/16492/fd
total 0

l-wx------ 1 root root 64 Apr 14 09:50 3 -> /a
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ the path is reported incorrectly too
$ cat /proc/16492/fdinfo/3
pos: 0
flags: 0100001
mnt_id: 164
$ cat /proc/self/mountinfo | grep over
163 77 0:42 / /home/avagin/tmp/z rw,relatime shared:109 - overlay overlay rw,lowerdir=a,upperdir=b,workdir=c
I think we need to report all this issues into lkml. Overlay is a new
file system, so we have a big chance that all of them will be fixed.
