Subject: [PATCH v2 19/22] run-command.c: don't copy "data" to "struct parallel_processes"
Date: Wed, 12 Oct 2022 11:01:27 +0200 [thread overview]
Message-ID: <patch-v2-19.22-9cbee2dfe76-20221012T084850Z-avarab@gmail.com> (raw)
In-Reply-To: <cover-v2-00.22-00000000000-20221012T084850Z-avarab@gmail.com>
As with the *_fn members removed in a preceding commit, let's not copy
the "data" member of the "struct run_process_parallel_opts" over to
the "struct parallel_processes". Now that we're passing the "opts"
down there's no reason to do so.
This makes the code easier to follow, as we have a "const" attribute
on the "struct run_process_parallel_opts", but not "struct
parallel_processes". We do not alter the "ungroup" argument, so
storing it in the non-const structure would make this control flow
less obvious.
