From 31156ec378c2ed10330c8c06bbf36fb7d7a55506 Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Tue, 13 Mar 2018 17:28:39 +0100 Subject: [PATCH] bsg-lib: introduce a timeout field in struct bsg_job The zfcp driver wants to know the timeout for a bsg job, so add a field to struct bsg_job for it in preparation of not exposing the request to the bsg-lib users.
