From 0718afd47f70cf46877c39c25d06b786e1a3f36c Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Thu, 1 Jun 2023 11:44:52 +0200 Subject: block: introduce holder ops Add a new blk_holder_ops structure, which is passed to blkdev_get_by_* and installed in the block_device for exclusive claims. It will be used to allow the block layer to call back into the user of the block device for thing like notification of a removed device or a device resize.
