[PATCH 2/6] bcache: make kobj_type structures constant

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]


From: Thomas Weißschuh <linux@xxxxxxxxxxxxxx>

Since commit ee6d3dd4ed48 ("driver core: make kobj_type constant.")
the driver core allows the usage of const struct kobj_type.

Take advantage of this to constify the structure definitions to prevent
modification at runtime.
