category: bugfix
bugzilla: https://gitee.com/openeuler/kernel/issues/I69NMA
CVE: CVE-2022-47946

Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=0f544353fec8e717d37724d95b92538e1de79e86

--------------------------------

Hunk extracted from commit 70aacfe6
upstream.

If the sqpoll thread has died, the out condition doesn't remove the
waiting task from the waitqueue. The goto and check are not needed, just
make it a break condition after setting the error value. That ensures
that we always remove ourselves from sqo_sq_wait waitqueue.
