Subject: [PATCH v3] scsi/bfa: use designated initializers
Date: Thu, 20 Apr 2017 15:00:02 -0700 [thread overview]
Message-ID: <20170420220002.GA65324@beast> (raw)
Prepare to mark sensitive kernel structures for randomization by making
sure they're using designated initializers. This also initializes the
array members using the enum used to look up __port_action entries.
Signed-off-by: Kees Cook <keescook@chromium.org>

v3:
- drop bfa_module_s changes, since that has been removed entirely; hch.
- init array with enum literals; hch.
