I want to write a kernel module that will perform read write operations on RAID device through md device driver.
The solution i found is to generate read write call using ll_rw_block interface. Is this correct soln ? if yes then how should i go for it i.e. how to initialise buffer_head struct parameter etc...
and if no please suggest what should i do ???
Kernel 2.4.20 using md device with RAID1 personality.
