Subject: io_uring: kill unnecessary io_run_ctx_fallback() in io_ring_exit_work()
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=914390bcfdd6351a4d308da7f43294476ea7d3bf;p=linux.git

io_uring: kill unnecessary io_run_ctx_fallback() in io_ring_exit_work()

We already run the fallback task_work in io_uring_try_cancel_requests(),
no need to duplicate at ring exit explicitly.
