Subject: move bd_mutex to the gendisk
Date: Tue, 30 Mar 2021 18:17:12 +0200 [thread overview]
Message-ID: <20210330161727.2297292-1-hch@lst.de> (raw)
Hi all,
this series first cleans up gendisk allocation in the md driver to remove
the ERESTARTSYS hack in blkdev_get, then further refactors blkdev_get
and then finally moves bd_mutex into the gendisk as having separate locks
for the whole device vs partitions just complicates locking in places that
add an remove partitions a lot.
Note that this series sits on top of the for-5.13/drivers branch as that
has the ->revalidate_disk cleanup.
