Subject: [PATCH] vhost: scsi: constify target_core_fabric_ops structures
Date: Mon, 9 Jan 2017 20:51:02 +0530 [thread overview]
Message-ID: <1483975262-1260-1-git-send-email-bhumirks@gmail.com> (raw)
Declare target_core_fabric_ops strucrues as const as they are only
passed as an argument to the functions target_register_template and
target_unregister_template. The arguments are of type const struct
target_core_fabric_ops *, so target_core_fabric_ops structures having
this property can be declared const.
Done using Coccinelle:
