[Qemu-block] [PATCH v2 27/32] qcow2: Rename l2_table in qcow2_alloc_comp


From: Alberto Garcia
Subject: [Qemu-block] [PATCH v2 27/32] qcow2: Rename l2_table in qcow2_alloc_compressed_cluster_offset()
Date: Fri, 15 Dec 2017 13:53:55 +0100

This function doesn't need any changes to support L2 slices, but since
it's now dealing with slices intead of full tables, the l2_table
variable is renamed for clarity.
