  "message": "UBI: fix atomic LEB change problems\n\nWhen the UBI device is nearly full, i.e. all LEBs are mapped, we have\nonly one spare LEB left - the one we reserved for WL purposes. Well,\nI do not count the LEBs which were reserved for bad PEB handling -\nsuppose NOR flash for simplicity. If an \"atomic LEB change operation\"\nis run, and the WL unit is moving a LEB, we have no spare LEBs to\nfinish the operation and fail, which is not good. Moreover, if there\nare 2 or more simultanious \"atomic LEB change\" requests, only one of\nthem has chances to succeed, the other will fail with -ENOSPC. Not\ngood either.\n\nThis patch does 2 things:\n1. Reserves one PEB for the \"atomic LEB change\" operation.\n2. Serealize the operations so that only on of them may run\n   at a time (by means of a mutex).\n\nPointed-to-by: Brijesh Singh \u003cbrijesh.s.singh@gmail.com\u003e\nSigned-off-by: Artem Bityutskiy \u003cArtem.Bityutskiy@nokia.com\u003e\n",
