[Bug 1094019] Re: Linux's getdents gets /.. inode number from host system under LXC

[Ahmed Kamal]

Hi Serge,

You need to compile the C code on
http://www.kernel.org/doc/man-pages/online/pages/man2/getdents.2.html
and run it to see this issue. It's "getdent" sys-call that sees different
numbers. Please confirm
