From a4e872f7b629c9f5a4f83bb2a84ece91b89ade67 Mon Sep 17 00:00:00 2001 From: Janani Ravichandran Date: Wed, 10 Feb 2016 22:47:33 -0500 Subject: [PATCH] staging: lustre: Modify arguments of sizeof() to pointer variables Take the size of a dereference to a variable rather than the associated type, to make the code more resistant to type changes in the future. The type of the pointer variable here is the same as the type in the argument that is being replaced in sizeof().
