[PATCH 0/3] name_is_dot* cleanup

[Amir Goldstein <amir73il@gmail.com>]

Miklos,

Following the syzbot ovl bug report and a fix by Qing Wang,
I decided to follow up with a small vfs cleanup of some
open coded version of checking "." and ".." name in readdir.

The fix patch is applied at the start of this cleanup series to allow
for easy backporting, but it is not an urgent fix so I don't think
there is a need to fast track it.

Christian,

I am assuming that you would want to take the vfs cleanup
via your tree, so might as well take the ovl adjacent patches
with it.

If you want me to drive this entire series via ovl tree, please
ack the vfs cleanup patch.

Thanks,
Amir.
