From 14f5ff5df37a8fabe2d25b1e64df7e010cc87db9 Mon Sep 17 00:00:00 2001 From: Al Viro Date: Mon, 5 Mar 2012 13:38:09 -0500 Subject: [PATCH] VM: make zap_page_range() return void ... since all callers ignore its return value and it's been useless since commit 97a894136f29802da19a15541de3c019e1ca147e (mm: Remove i_mmap_lock lockbreak) anyway.
