[PATCH v3 14/15] merge-recursive: give callers of handle_content_merge() access to contents

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Pass a merge_file_info struct to handle_content_merge() so that the
callers can access the oid and mode of the result afterward.
