Subject: [PATCH 1/7] make_transient_cache_entry(): optionally alloc from mem_pool
Date: Thu, 22 Apr 2021 12:17:47 -0300 [thread overview]
Message-ID: <f870040bfb3e73ee8cd27352b0acc65bb54be560.1619104091.git.matheus.bernardino@usp.br> (raw)
In-Reply-To: <cover.1619104091.git.matheus.bernardino@usp.br>
Allow make_transient_cache_entry() to optionally receive a mem_pool
struct in which it should allocate the entry. This will be used in the
following patch, to store some transient entries which should persist
until parallel checkout finishes.
