Hi,
I have attached InterSbull.c. I have sbull and sbull1 block drivers with major number 254, 253 respectively. In InterSbull.c, in init_module, I am replacing sbull's ( major 254 ) make_request_fn with my kti_make_request_fn. Everything is going fine with this.
But when I want to write same data to other sbull1 (major number 253 ). I am getting kernel panic. When I do an I/O to sbull device ( major number 254 ). In WRITE, in kti_make_request_fn I am using brw_kiovec to send I/O to 253 device
Could you help me what can be the issue in this? Any help is appreciated.
Thanks and regards, Srinivas
