I have a USB card reader. It is capable of read/write CF, Smartmedia etc. It works fine on Linux. While looking into driver, I found that the driver works between USB host controller and SCSI layer. Just for learning purpose, I want to write it as block driver. The functions which performs read/write from the device are blocking. Therefore I can't call these functions directly from request function. Can somebody tell me how can I call blocking functions from request function. I tried to set BH but it didn't work.
