From be6aef604920406b348acf3be6e6e8db55696386 Mon Sep 17 00:00:00 2001 From: Josef Bacik Date: Mon, 22 Oct 2012 15:43:12 -0400 Subject: [PATCH] Btrfs: Use btrfs_update_inode_fallback when creating a snapshot On a really full file system I was getting ENOSPC back from btrfs_update_inode when trying to update the parent inode when creating a snapshot. Just use the fallback method so we can update the inode and not have to worry about having a delayed ref.
