Subject: [PATCH] 9p: Constify static struct v9fs_attr_group
Date: Fri, 8 Jan 2021 23:46:50 +0100 [thread overview]
Message-ID: <20210108224650.25872-1-rikard.falkeborn@gmail.com> (raw)
The only usage of v9fs_attr_group is to pass its address to
sysfs_create_group() and sysfs_create_group(), both which takes pointers
to const struct attribute_group. Make it const to allow the compiler to
put it in read-only memory.
