Christian Brauner f61033390b block: assert that we're not holding open_mutex over blk_report_disk_dead ... blk_report_disk_dead() has the following major callers: (1) del_gendisk() (2) blk_mark_disk_dead() Since del_gendisk() acquires disk->open_mutex it's clear that all callers are assumed to be called without disk->open_mutex held. In turn, blk_report_disk_dead() is called without disk->open_mutex held in del_gendisk(). All callers of blk_mark_disk_dead() call it without disk->open_mutex as well. Ensure that it is clear that blk_report_disk_dead() is called without disk->open_mutex on purpose by asserting it and a comment in the code.
