  "message": "blktrace: remove debugfs entries on bad path\n\ndebugfs directory entries for devices are not removed on some\nof the failure pathes in do_blk_trace_setup().\nOne way to reproduce is to start blktrace on multiple devices\nwith insufficient Vmalloc space: Devices will fail with\na message like this:\n\n\tBLKTRACESETUP(2) /dev/sdu failed: 5/Input/output error\n\nIf so, the respective entries in debugfs\n(e.g. /sys/kernel/debug/block/sdu) will remain and subsequent\nattempts to start blktrace on the respective devices will not\nsucceed due to existing directories.\n\n[ Impact: fix /debug/tracing file cleanup corner case ]\n\nSigned-off-by: Stefan Raspl \u003cstefan.raspl@linux.vnet.ibm.com\u003e\nAcked-by: Li Zefan \u003clizf@cn.fujitsu.com\u003e\nCc: Li Zefan \u003clizf@cn.fujitsu.com\u003e\nCc: schwidefsky@de.ibm.com\nCc: heiko.carstens@de.ibm.com\nLKML-Reference: \u003c4A1266CC.5040801@linux.vnet.ibm.com\u003e\nSigned-off-by: Ingo Molnar \u003cmingo@elte.hu\u003e\n",
