From: Daniel Jordan <daniel.m.jordan@oracle.com> stable inclusion from stable-5.10.77 commit 58722323d4bc7e7fb9e1e4397551f7a02f2f2757 bugzilla: 185677 https://gitee.com/openeuler/kernel/issues/I4IAP7 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=... -------------------------------- commit 1d9d6fd21ad4a28b16ed9ee5432ae738b9dc58aa upstream. sk->sk_err contains a positive number, yet async_wait.err wants the opposite. Fix the missed sign flip, which Jakub caught by inspection.
