linux-toradex.git/include/linux/bsg-lib.h, branch T20_LinuxImageV2.0Beta1_20121218 Linux kernel for Apalis and Colibri modules block: add bsg helper library 2011-07-31T20:05:09+00:00 Mike Christie michaelc@cs.wisc.edu 2011-07-31T20:05:09+00:00 aa387cc895672b00f807ad7c734a2defaf677712 This moves the FC classes bsg code to the block layer and makes it a lib so that other classes like iscsi and SAS can use it. It is helpful because working with the request queue, bios, creating scatterlists, etc are a pain that the LLD does not have to worry about with normal IOs and should not have to worry about for bsg requests.
