Hi all, Following discard in the last merge window, this series also makes secure erase and discard interruptible by fatal signals. The secure erase side is a straight port of the discard support. Unfortunately I don't have a way to test it, so I'm adding the eMMC maintainer as that is where the support originated so maybe they can give it a spin? (just do a blkdiscard -f -s /dev/<dev> and then Ctrl+C) The write zeroes support is a bit different as it is more complex due to the fallback code and there already is a helper taking flags that we piggy back on. This side has been extensively tested.
