Subject: [PATCH 5/5] virtio_console: Constify some static variables
Date: Wed, 1 Jul 2020 22:09:50 +0200 [thread overview]
Message-ID: <20200701200950.30314-6-rikard.falkeborn@gmail.com> (raw)
In-Reply-To: <20200701200950.30314-1-rikard.falkeborn@gmail.com>
The id_table and feature_table pointers in struct virtio_driver are
pointers to const. Mark the corresponding static variables const to
allow the compiler to put them in read-only memory.
Before:
text data bss dec hex filename
25447 713 76 26236 667c drivers/char/virtio_console.o
After:
text data bss dec hex filename
25488 673 76 26237 667d drivers/char/virtio_console.o
