From: Aleksei Oladko Date: Sat, 21 Mar 2026 21:59:08 +0000 (+0000) Subject: selftests: net: io_uring_zerocopy: enable io_uring for the test X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=9d463f7863f2cc3722da9c670c88158409cb7c42;p=thirdparty%2Fkernel%2Fstable.git selftests: net: io_uring_zerocopy: enable io_uring for the test The io_uring_zerocopy.sh kselftest assumes that io_uring support is enabled on the host system. When io_uring is disabled via the kernel.io_uring_disabled sysctl, the test fails. Explicitly enable io_uring for the test by setting kernel.io_uring_disabled=0. Save the original value of kernel.io_uring_disabled before changing it and restore it in cleanup handler to ensure the system state is restored regardless of test outcome.
