  "message": "efi_pstore: Add a sequence counter to a variable name\n\n[Issue]\n\nCurrently, a variable name, which identifies each entry, consists of type, id and ctime.\nBut if multiple events happens in a short time, a second/third event may fail to log because\nefi_pstore can\u0027t distinguish each event with current variable name.\n\n[Solution]\n\nA reasonable way to identify all events precisely is introducing a sequence counter to\nthe variable name.\n\nThe sequence counter has already supported in a pstore layer with \"oopscount\".\nSo, this patch adds it to a variable name.\nAlso, it is passed to read/erase callbacks of platform drivers in accordance with\nthe modification of the variable name.\n\n  \u003cbefore applying this patch\u003e\n a variable name of first event: dump-type0-1-12345678\n a variable name of second event: dump-type0-1-12345678\n\n  type:0\n  id:1\n  ctime:12345678\n\n If multiple events happen in a short time, efi_pstore can\u0027t distinguish them because\n variable names are same among them.\n\n  \u003cafter applying this patch\u003e\n\n it can be distinguishable by adding a sequence counter as follows.\n\n a variable name of first event: dump-type0-1-1-12345678\n a variable name of Second event: dump-type0-1-2-12345678\n\n  type:0\n  id:1\n  sequence counter: 1(first event), 2(second event)\n  ctime:12345678\n\nIn case of a write callback executed in pstore_console_write(), \"0\" is added to\nan argument of the write callback because it just logs all kernel messages and\ndoesn\u0027t need to care about multiple events.\n\nSigned-off-by: Seiji Aguchi \u003cseiji.aguchi@hds.com\u003e\nAcked-by: Rafael J.
