"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nxfs: restore nofs context unconditionally in xfs_trans_roll\n\nWhen __xfs_trans_commit() fails in xfs_trans_roll(), the NOFS context\nis cleared but only restored in the success path. This leaves the\nerror path without nofs protection, causing a circular lock dependency\nbetween xfs_nondir_ilock_class and fs_reclaim:\n\n CPU0 CPU1\n ---- ----\n lock(&xfs_nondir_ilock_class);\n lock(fs_reclaim);\n lock(&xfs_nondir_ilock_class);\n lock(fs_reclaim);\n\nFix this by moving xfs_trans_set_context() before the error check so\nthat nofs context is always restored on the new transaction."
