From 23b5c50945f2294add0137799400329c0ebba290 Mon Sep 17 00:00:00 2001 From: "Aneesh Kumar K.V" Date: Thu, 4 Feb 2010 11:33:03 -0500 Subject: Btrfs: apply updated fallocate i_size fix This version of the i_size fix for fallocate makes sure we only update the i_size when the current fallocate is really operating outside of i_size.
