  "message": "ring-buffer: Move disabled check into preempt disable section\n\nThe ring buffer resizing and resetting relies on a schedule RCU\naction. The buffers are disabled, a synchronize_sched() is called\nand then the resize or reset takes place.\n\nBut this only works if the disabling of the buffers are within the\npreempt disabled section, otherwise a window exists that the buffers\ncan be written to while a reset or resize takes place.\n\nCc: stable@kernel.org\nReported-by: Li Zefan \u003clizf@cn.fujitsu.com\u003e\nSigned-off-by: Lai Jiangshan \u003claijs@cn.fujitsu.com\u003e\nLKML-Reference: \u003c4B949E43.2010906@cn.fujitsu.com\u003e\nSigned-off-by: Steven Rostedt \u003crostedt@goodmis.org\u003e\n",
