Subject: [PATCH 0/4] clean early submission path
Date: Wed, 8 Apr 2020 08:58:42 +0300 [thread overview]
Message-ID: <cover.1586325467.git.asml.silence@gmail.com> (raw)
This is mainly in preparation for future changes, but looks nice
by itself. The last patch fixes a mild vulnerability.
Pavel Begunkov (4):
io_uring: simplify io_get_sqring
io_uring: alloc req only after getting sqe
io_uring: remove req init from io_get_req()
io_uring: don't read user-shared sqe flags twice
