[Drbd-dev] [PATCH 2/3] lru_cache: Improve two size determinations in lc_create()

[Markus Elfring]

Date: Wed, 29 Mar 2023 15:00:13 +0200

Replace the specification of data structures by pointer dereferences
as the parameter for the operator “sizeof” to make the corresponding size
determination a bit safer according to the Linux coding style convention.
