Eric Biggers 84fe3ca6e7 block: don't delete queue kobject before its children ... [ Upstream commit 0f69288253e9fc7c495047720e523b9f1aba5712 ] kobjects aren't supposed to be deleted before their child kobjects are deleted. Apparently this is usually benign; however, a WARN will be triggered if one of the child kobjects has a named attribute group: sysfs group 'modes' not found for kobject 'crypto' WARNING: CPU: 0 PID: 1 at fs/sysfs/group.c:278 sysfs_remove_group+0x72/0x80 ...
