category: bugfix
bugzilla: 187376, https://gitee.com/src-openeuler/kernel/issues/I5IM3T
CVE: CVE-2022-2327

Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=fb2fbb3c10d779c0163c9c2c7ca1aeb75ef3f7ca

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

A previous commit ended up enabling file tracking for iopoll requests,
which conflicts with both of them using the same list entry for tracking.
Add a separate list entry just for iopoll requests, avoid this issue.

No upstream commit exists for this issue.
