Message-ID: <20140519174824.062bcf53@chukar.edge2.net>
Date: Mon, 19 May 2014 17:48:24 -0600
From: Jake Edge <jake@....net>
To: Greg Kroah-Hartman <gregkh@...uxfoundation.org>
Cc: Jason Cooper <jason@...edaemon.net>, devel@...verdev.osuosl.org,

Subject: [PATCH v3 1/1] staging/skein: rename files and clean up directory
structure
Clean up file names and locations. Get rid of include/ directory and move
those up to the top-level. Rename files to get rid of upper case. Remove
skeinBlockNo3F.c as it was unused (temporary file or something?).
Signed-off-by: Jake Edge <jake@....net>
---
v3: against staging-next branch of staging tree
v2: use git format-patch -M as suggested by Joe Perches
