Subject: [PATCH 05/11] UAPI: coda: Don't use internal kernel structs in UAPI
Date: Wed, 05 Sep 2018 16:55:10 +0100 [thread overview]
Message-ID: <153616291029.23468.16421004714304578585.stgit@warthog.procyon.org.uk> (raw)
In-Reply-To: <153616286704.23468.584491117180383924.stgit@warthog.procyon.org.uk>
The size and layout of internal kernel structures may not be relied upon
outside of the kernel and may even change in a containerised environment if
a container image is frozen and shifted to another machine.
Excise these from Coda's upc_req struct.
