[Qemu-devel] [PULL 49/55] qcow2: Rename l2_table in count_contiguous_clu


From: Kevin Wolf
Subject: [Qemu-devel] [PULL 49/55] qcow2: Rename l2_table in count_contiguous_clusters()
Date: Tue, 13 Feb 2018 18:05:23 +0100

From: Alberto Garcia <address@hidden>

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.
