Subject: [PATCH v4 14/19] builtin/checkout.c: complete parallel checkout support
Date: Wed,  4 Nov 2020 17:33:13 -0300	[thread overview]
Message-ID: <fb9f2f580c5ae02bbeb8117c85bc24307320aa59.1604521276.git.matheus.bernardino@usp.br> (raw)
In-Reply-To: <cover.1604521275.git.matheus.bernardino@usp.br>

There is one code path in builtin/checkout.c which still doesn't benefit
from parallel checkout because it calls checkout_entry() directly,
instead of unpack_trees(). Let's add parallel support for this missing
spot as well. Note: the transient cache entries allocated in
checkout_merged() are now allocated in a mem_pool which is only
discarded after parallel checkout finishes. This is done because the
entries need to be valid when run_parallel_checkout() is called.
