Subject: [PATCH v4 01/10] commit-graph: rename 'num_extra_edges' variable to 'num_large_edges'
Date: Thu, 22 Nov 2018 15:39:13 +0000	[thread overview]
Message-ID: <20181122153922.16912-2-avarab@gmail.com> (raw)
In-Reply-To: <20181122132823.9883-1-avarab@gmail.com>

From: SZEDER Gábor <szeder.dev@gmail.com>

The commit graph file format describes an optional 'Large Edge List'
chunk, and the function writing out this chunk is called
write_graph_chunk_large_edges().  Then there are two functions in
'commit-graph.c', namely write_graph_chunk_data() and
write_commit_graph(), which have a local variable called
'num_extra_edges'.

It can be confusing on first sight whether large edges and extra edges
refer to the same thing or not, but they do, so let's rename those
variables to 'num_large_edges'.
