From 681eece4cd021fd5d85637d0e67b7eae45292f8e Mon Sep 17 00:00:00 2001 From: Josef Bacik Date: Mon, 22 Nov 2010 18:55:39 +0000 Subject: [PATCH] Btrfs: make sure new inode size is ok in fallocate We have been failing xfstest 228 forever, because we don't check to make sure the new inode size is acceptable as far as RLIMIT is concerned. Just check to make sure it's ok to create a inode with this new size and error out if not. With this patch we now pass 228.
