From 329061d3e2f9a0082a097e9558bd5497098586c6 Mon Sep 17 00:00:00 2001 From: Jens Axboe Date: Wed, 25 May 2022 20:31:09 -0600 Subject: io_uring: move poll handling into its own file Add a io_poll_issue() rather than export the general task_work locking and io_issue_sqe(), and put the io_op_defs definition and structure into a separate header file so that poll can use it.
