CVE-2026-80804

In the Linux kernel, the following vulnerability has been resolved:

xfs: restore nofs context unconditionally in xfstransroll

When __xfstranscommit() fails in xfstransroll(), the NOFS context is cleared but only restored in the success path. This leaves the error path without nofs protection, causing a circular lock dependency between xfsnondirilockclass and fsreclaim:

   CPU0                    CPU1
   ----                    ----

lock(&xfsnondirilockclass); lock(fsreclaim); lock(&xfsnondirilockclass); lock(fsreclaim);

Fix this by moving xfstransset_context() before the error check so that nofs context is always restored on the new transaction.
