Subject: fix delayed holder tracking v2
Date: Sun, 30 Oct 2022 16:31:12 +0100 [thread overview]
Message-ID: <20221030153120.1045101-1-hch@lst.de> (raw)
Hi all,
this series tries to fix the delayed holder tracking that is only used by
dm by moving it into dm, where we can track the lifetimes much better.
Changes since v1:
- don't blow away ->bd_holder_dir in del_gendisk or add_disk failure
as the holder unregistration references it
- add an extra cleanup patch
