[PATCH v4 07/27] revisions API users: add straightforward release_revisions()

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

 



Add a release_revisions() to various users of "struct rev_list" in
those straightforward cases where we only need to add the
release_revisions() call to the end of a block, and don't need to
e.g. refactor anything to use a "goto cleanup" pattern.
