From 2638c20876734f986fd91cfbe196483835ed7095 Mon Sep 17 00:00:00 2001 From: Al Viro Date: Sun, 28 Apr 2024 19:01:39 -0400 Subject: missing helpers: bdev_unhash(), bdev_drop() bdev_unhash(): make block device invisible to lookups by device number bdev_drop(): drop reference to associated inode. Both are internal, for use by genhd and partition-related code - similar to bdev_add(). The logics in there (especially the lifetime-related parts of it) ought to be cleaned up, but that's a separate story; here we just encapsulate getting to associated inode.
