  "message": "UBIFS: use an IS_ERR test rather than a NULL test\n\nIn case of error, the function kthread_create returns an ERR pointer,\nbut never returns a NULL pointer. So a NULL test that comes before an\nIS_ERR test should be deleted.\n\nThe semantic match that finds this problem is as follows:\n(http://www.emn.fr/x-info/coccinelle/)\n\n// \u003csmpl\u003e\n@match_bad_null_test@\nexpression x, E;\nstatement S1,S2;\n@@\nx \u003d kthread_create(...)\n... when !\u003d x \u003d E\n* if (x \u003d\u003d NULL)\nS1 else S2\n// \u003c/smpl\u003e\n\nSigned-off-by: Julien Brunel \u003cbrunel@diku.dk\u003e\nSigned-off-by: Julia Lawall \u003cjulia@diku.dk\u003e\nSigned-off-by: Artem Bityutskiy \u003cArtem.Bityutskiy@nokia.com\u003e\n",
