The\nparent will call __bionic_atfork_run_prepare() to lock the handler_mutex,\nand need both the parent and child to unlock their own copy of handler_mutex\nafter fork. At that time, the owner of hanlder_mutex is set as the parent.\nIf we apply the kernel_id fix, then the child\u0027s kernel_id will be set as\nchild\u0027s tid.\nThe handler_mutex is a recursive lock, and pthread_mutex_unlock(\u0026hander_mutex)\nwill fail because the mutex owner is the parent, while the current tid\n(__get_thread()-\u003ekernel_id) is child, not matched with the mutex owner.\nAt that time, the handler_mutex is left in lock state.If the child wants to\nfork other process after than, then it will try to lock handler_mutex, and\nthen be deadlocked.\n\nFix:\nSince the child has its own copy of vm space from the the parent, the\nchild space\u0027s handler_mutex should be reset to the initialized state.\n\nChange-Id: I3907dd9a153418fb78862f2aa6d0302c375d9e27\nSigned-off-by: Jack Ren \u003cjack.ren@intel.com\u003e\nSigned-off-by: Chenyang Du \u003cchenyang.du@intel.com\u003e\nSigned-off-by: Bruce Beare \u003cbruce.j.beare@intel.com\u003e\n\nChange-Id: Ic8072f366a877443a60fe215f3c00b3df5a259c8\n"
