Hello,
these patches fix races happening when devices are frequently destroyed and
recreated in association of block device inode with corresponding gendisk.
Generally when such race happen it results in use-after-free issues, block
device page cache inconsistencies, or other problems. I have verified these
patches fix use-after-free issues that could be reproduced by frequent creation
and destruction of loop device. Hou Tao has verified that races reported by
him in [1] related to gendisk-blkdev association were also fixed. Jens, can
you please merge these patches? Thanks!
Changes since v1:
* Added tested-by tags
