From 3e05b222382ec67dce7358d50b6006e91d028d8b Mon Sep 17 00:00:00 2001 From: Gabriel Krisman Bertazi Date: Tue, 18 Jun 2024 22:06:18 -0400 Subject: io_uring: Fix probe of disabled operations io_probe checks io_issue_def->not_supported, but we never really set that field, as we mark non-supported functions through a specific ->prep handler. This means we end up returning IO_URING_OP_SUPPORTED, even for disabled operations. Fix it by just checking the prep handler itself.
