3.11.10.3 -stable review patch. If anyone has any objections, please let me know. ------------------ From: Josef Bacik <jbacik@xxxxxxxxxxxx> commit ed9e8af88e2551aaa6bf51d8063a2493e2d71597 upstream. I added an assert to make sure we were looking up aligned offsets for csums and I tripped it when running xfstests. This is because log_one_extent was checking if block_start == 0 for a hole instead of EXTENT_MAP_HOLE. This worked out fine in practice it seems, but it adds a lot of extra work that is uneeded. With this fix I'm no longer tripping my assert.
