[PATCH 1/2] virtiofs: Improve three size determinations

[Markus Elfring]

From: Markus Elfring <elfr...@users.sourceforge.net>
Date: Fri, 29 Dec 2023 08:42:04 +0100

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.

This issue was detected by using the Coccinelle software.
