From 819630bd6f86ac8998c7df9deddb6cee50e9e22d Mon Sep 17 00:00:00 2001 From: Pavel Begunkov Date: Mon, 3 Nov 2025 13:53:13 +0000 Subject: io_uring/zcrx: remove sync refill uapi There is a better way to handle the problem IORING_REGISTER_ZCRX_REFILL solves. The uapi can also be slightly adjusted to accommodate future extensions. Remove the feature for now, it'll be reworked for the next release.
