Subject: [PATCH 03/12] io_uring: further deduplicate file slot selection
Date: Sun, 28 Feb 2021 22:35:11 +0000 [thread overview]
Message-ID: <6f2b93aceecf5591b845542d18babae13c8bbef0.1614551467.git.asml.silence@gmail.com> (raw)
In-Reply-To: <[email protected]>
io_fixed_file_slot() and io_file_from_index() behave pretty similarly,
DRY and call one from another.
