CVE-2026-23109

In the Linux kernel, the following vulnerability has been resolved: fs/writeback: skip AS_NO_DATA_INTEGRITY mappings in wait_sb_inodes() Above the while() loop in wait_sb_inodes(), we document that we must wait for all pages under writeback for data integrity. Consequently, if a mapping, like fuse, traditionally does not have data integrity semantics, there is no need to wait at all; we can simply skip these inodes. This restores fuse back to prior behavior where syncs are no-ops. This fixe
