  "message": "Btrfs: fix oops on page-\u003emapping-\u003ehost during writepage\n\nThe extent_io writepage call updates the writepage index in the inode\nas it makes progress.  But, it was doing the update after unlocking the page,\nwhich isn\u0027t legal because page-\u003emapping can\u0027t be trusted once the page\nis unlocked.\n\nThis lead to an oops, especially common with compression turned on.  The\nfix here is to update the writeback index before unlocking the page.\n\nSigned-off-by: Chris Mason \u003cchris.mason@oracle.com\u003e\n",
