Subject: [PATCH 05/11] UAPI: coda: Move kernel internals out of public view [ver #2]
Date: Thu, 06 Sep 2018 10:18:57 +0100	[thread overview]
Message-ID: <153622553762.14298.10096062467394188420.stgit@warthog.procyon.org.uk> (raw)
In-Reply-To: <153622549721.14298.8116794954073122489.stgit@warthog.procyon.org.uk>

The upc_req struct and the CODA_REQ_* constants are kernel internals and
shouldn't have been exposed to userspace.  Indeed, the upc_req struct
contains other kernel internal structs.

Move them to include/linux/coda_psdev.h.
