From b6777c40c79168d938c30b5b7471fbd64bca109c Mon Sep 17 00:00:00 2001 From: Miklos Szeredi Date: Tue, 26 Oct 2010 14:22:27 -0700 Subject: [PATCH] fuse: use clear_highpage() and KM_USER0 instead of KM_USER1 Commit 7909b1c640 ("fuse: don't use atomic kmap") removed KM_USER0 usage from fuse/dev.c. Switch KM_USER1 uses to KM_USER0 for clarity. Also replace open coded clear_highpage().
