Josef Bacik 79124f18b3 fs: add hole punching to fallocate ... Hole punching has already been implemented by XFS and OCFS2, and has the potential to be implemented on both BTRFS and EXT4 so we need a generic way to get to this feature. The simplest way in my mind is to add FALLOC_FL_PUNCH_HOLE to fallocate() since it already looks like the normal fallocate() operation. I've tested this patch with XFS and BTRFS to make sure XFS did what it's supposed to do and that BTRFS failed like it was supposed to.
