Hi, I was wondering if there is an alternate way than opening a file in kernel space. I am not sure if I can effectively open an device (the block device specifically) in kernel space. Is there a global array variable of all the block devices recognized by the kernel that I can scan to find out the the exact one for a corresponding dev entry (e.g /dev/hda). This is for 2.6 kernel.
