  "message": "[S390] vmur: Use wait queue instead of mutex to serialize open\n\nIf user space opens a unit record device node then vmur is leaving the kernel\nwith lock open_mutex still held to prevent other processes from opening the\ndevice simultaneously. This causes lockdep to complain about a lock held when\nreturning to user space.\nNow the mutex is replaced by a wait queue to serialize device open.\n\nSigned-off-by: Frank Munzert \u003cmunzert@de.ibm.com\u003e\nSigned-off-by: Martin Schwidefsky \u003cschwidefsky@de.ibm.com\u003e\nSigned-off-by: Heiko Carstens \u003cheiko.carstens@de.ibm.com\u003e\n",
