Subject: [PATCH v2 1/9] commit: avoid allocation in clear_commit_marks_many()
Date: Mon, 25 Dec 2017 18:43:37 +0100	[thread overview]
Message-ID: <d37d0e0d-c703-a70c-cf0b-969e54473557@web.de> (raw)
In-Reply-To: <ac4c77a1-6403-ca20-2021-50c99201915a@web.de>

Pass the entries of the commit array directly to clear_commit_marks_1()
instead of adding them to a commit_list first.  The function clears the
commit and any first parent without allocation; only higher numbered
parents are added to a list for later treatment.  This change extends
that optimization to clear_commit_marks_many().
