Subject: [PATCH 03/12] reflog: change one->many worktree->refnames to use a string_list
Date: Tue, 30 Nov 2021 22:38:05 +0100 [thread overview]
Message-ID: <patch-03.12-5a54b04a13e-20211130T213319Z-avarab@gmail.com> (raw)
In-Reply-To: <cover-00.12-00000000000-20211130T213319Z-avarab@gmail.com>
Change the FLEX_ARRAY pattern added in bda3a31cc79 (reflog-expire:
Avoid creating new files in a directory inside readdir(3) loop,
2008-01-25) the string-list API instead.
This does not change any behavior, allows us to delete much of this
code as it's replaced by things we get from the string-list API for
free, as a result we need just one struct to keep track of this data,
instead of two.
