[RFC][PATCH 0/2] ovl: make room to store state flags in dentry

[Amir Goldstein <amir73il@gmail.com>]

Miklos,

This is a prep work I have done some time ago to make room
for some extra state flags on the dentry.

I converted the boolean opaque field to a flag as an example.

An example for more flags could be:
- this is a copy up file which needs to get st_ino from lower
- this is an O_TEMP copy up from open for read that needs to be
  linked to upper dir on open for write

  ovl: store path type in dentry
  ovl: cram opaque boolean into type flags
