Subject: add a ZONE_RESET_ALL uring cmd
Date: Wed, 15 Jul 2026 08:37:14 +0200 [thread overview]
Message-ID: <20260715063734.2933511-1-hch@lst.de> (raw)
Hi Jens,
this series adds a new ZONE_RESET_ALL uring cmd, and cleans up the discard
support a little bit in preparation for that.
This command is useful to speed up workloads that need to initialize a
large number (or even a small > 1 number) of disks.
