Hi, all:
When I "ls" a overlayfs directory which has a whiteout device in it's upper dir,
and got a strange output like this (aaa is a whiteout in upper):
[ETO test]# ll -i
ls: cannot access 'aaa': No such file or directory
total 3
? ?????????? ? ? ? ? ? aaa
157633 drwxr-xr-x 1 root root 96 3月 31 2017 hello
157634 drwxr-xr-x 2 root root 96 3月 31 2017 open
157632 drwxr-xr-x 1 root root 128 3月 29 04:54 ssh
But if I use "tree" to list the files , there is no whiteout device in
the test(overlayfs root dir).
I got this output and it seems OK.
[ETO usb]# tree
.
├── lower
│ ├── aaa
│ ├── hello
│ │ └── uu
│ └── ssh
├── test
│ ├── hello
│ ├── open
│ │ └── uu
│ └── ssh
│ ├── aaa
│ └── bbb
├── upper
│ ├── aaa
│ ├── hello
│ │ └── uu
│ ├── open
│ │ └── uu
│ └── ssh
│ ├── aaa
│ └── bbb
If I am correct, I think if the upper dir has a whitout, and the root
directory of overlayfs
should not see this WHITEOUT DEV nor the file in the lower dir with
the same name.
Is this a overlayfs bug ???
