From be39f1968e33ca641af120a2d659421ad2225dea Mon Sep 17 00:00:00 2001 From: Dominik Dingel Date: Thu, 31 Oct 2013 10:01:16 +0100 Subject: [PATCH] s390/mm: page_table_realloc returns failure There is a possible race between setting has_pgste and reallocation of the page_table, change the order to fix this. Also page_table_alloc_pgste can fail, in that case we need to backpropagte this as -ENOMEM to the caller of page_table_realloc. Based on a patch by Christian Borntraeger .
