Subject[PATCH] fs: dlm: lockspace: constify kset_uevent_ops structures
Date
Declare kset_uevent_ops structure as const as it is only passed as
the second argument to the function kset_create_and_add. This
argument is of type const struct kset_uevent_ops *, so kset_uevent_ops
structures having this property can be declared const.
Done using Coccinelle:

@r1 disable optional_qualifier @
identifier i;
position p;

static struct kset_uevent_ops i@p = {...};

@ok1@
identifier r1.i;
position p;
expression e1,e2;

kset_create_and_add(e1,&i@p,e2)

@bad@
