Subject: [PATCH 0/3] blkpr: add read-keys and read-reservations commands
Date: Thu, 11 Dec 2025 11:09:53 -0500 [thread overview]
Message-ID: <20251211160956.1540114-1-stefanha@redhat.com> (raw)
New <linux/pr.h> ioctls make it possible to fetch the list of registered keys
and the details of the current reservation from a block device. The relevant
Linux commits are:
3e2cb9ee76c27 block: add IOC_PR_READ_RESERVATION ioctl
22a1ffea5f805 block: add IOC_PR_READ_KEYS ioctl
Add the appropriate commands to blkpr. Users can use these for troubleshooting
and cluster management tools may use them to query the state of persistent
reservations during recovery.
Stefan Hajnoczi (3):
blkpr: prepare for _IOR() ioctls
blkpr: add read-keys command
blkpr: add read-reservation command
