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.
