Subject: make secure erase and write zeroes ioctls interruptible as well
Date: Mon, 1 Jul 2024 18:51:10 +0200 [thread overview]
Message-ID: <20240701165219.1571322-1-hch@lst.de> (raw)
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.
