From 8258d4a574d3a8c01f0ef68aa26b969398a0e140 Mon Sep 17 00:00:00 2001 From: Andrew Morton Date: Wed, 11 Oct 2006 01:21:53 -0700 Subject: [PATCH] [PATCH] invalidate_inode_pages2_range() debug A failure in invalidate_inode_pages2_range() can result in unpleasant things happening in NFS (at least). Stick a WARN_ON_ONCE() in there so we can find out if it happens, and maybe why. (akpm: might be a -mm-only patch, we'll see..)
