From: Stefano Garzarella Date: Thu, 8 Jan 2026 11:44:19 +0000 (+0100) Subject: vsock/test: add a final full barrier after run all tests X-Git-Tag: v6.12.67~118 X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=b7e11383ef3cfd6462436a2ea99905a7de087c55;p=thirdparty%2Fkernel%2Fstable.git vsock/test: add a final full barrier after run all tests [ Upstream commit c39a6a277e0e67ffff6a8efcbbf7e7e23ce9e38c ] If the last test fails, the other side still completes correctly, which could lead to false positives. Let's add a final barrier that ensures that the last test has finished correctly on both sides, but also that the two sides agree on the number of tests to be performed.
