Hi Here I'm submitting the ramdisk discard patches for the next merge window. If you want to make some more changes, please let me now. Changes since version 2: There are no functional changes, I only moved the switch statement conversion to a separate patch, so that it's easier to review. Patch 1: introduce a switch statement in brd_submit_bio Patch 2: extend the rcu regions to cover read and write Patch 3: enable discard Patch 4: implement write zeroes Mikulas
