  "message": "ext4: Restore wbc-\u003erange_start in ext4_da_writepages()\n\nTo solve a lock inversion problem, we implement part of the\nrange_cyclic algorithm in ext4_da_writepages().  (See commit 2acf2c26\nfor more details.)\n\nAs part of that change wbc-\u003erange_start was modified by ext4\u0027s\nwritepages function, which causes its callers to get confused since\nthey aren\u0027t expecting the filesystem to modify it.  The simplest fix\nis to save and restore wbc-\u003erange_start in ext4_da_writepages.\n\nSigned-off-by: \"Theodore Ts\u0027o\" \u003ctytso@mit.edu\u003e\n",
