From 99eef8e9369abe009006b4fa7f6ca5086c09cf46 Mon Sep 17 00:00:00 2001 From: Dan Streetman Date: Wed, 6 Aug 2014 16:08:33 -0700 Subject: [PATCH] mm/zbud: change zbud_alloc size type to size_t Change the type of the zbud_alloc() size param from unsigned int to size_t. Technically, this should not make any difference, as the zbud implementation already restricts the size to well within either type's limits; but as zsmalloc (and kmalloc) use size_t, and zpool will use size_t, this brings the size parameter type in line with zsmalloc/zpool.
