## Description

In the Linux kernel, the following vulnerability has been resolved:  xfs: restore nofs context unconditionally in xfs_trans_roll  When __xfs_trans_commit() fails in xfs_trans_roll(), 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 xfs_nondir_ilock_class and fs_reclaim:         CPU0                    CPU1        ----                    ----   lock(&xfs_nondir_ilock_class);                                lock(fs_reclaim);                                lock(&xfs_nondir_ilock_class);   lock(fs_reclaim);  Fix this by moving xfs_trans_set_context() before the error check so that nofs context is always restored on the new transaction.
