Subject: [RFC][PATCH 0/2] ovl: make room to store state flags in dentry
Date: Tue, 21 Mar 2017 12:16:43 -0400	[thread overview]
Message-ID: <1490113005-28787-1-git-send-email-amir73il@gmail.com> (raw)

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
