From d663976dad68de9b2e3df59cc31f0a24ee4c4511 Mon Sep 17 00:00:00 2001 From: Pavel Begunkov Date: Thu, 13 Nov 2025 10:46:12 +0000 Subject: io_uring/zcrx: introduce IORING_REGISTER_ZCRX_CTRL It'll be annoying and take enough of boilerplate code to implement new zcrx features as separate io_uring register opcode. Introduce IORING_REGISTER_ZCRX_CTRL that will multiplex such calls to zcrx. Note, there are no real users of the opcode in this patch.
