.Improved protection against running BlueStore twice
Previously, advisory locking was used to protect against running BlueStore twice. This works well on baremetal deployments. However, when used on containers it would create unrelated inodes that targeted same `mknod b` block device. As a result, two containers might assume that they can have exclusive access which led to severe errors.
With this release, you can improve protection against running OSDs twice at the same time on one block device. You can reinforce advisory locking with O_EXCL open flag dedicated for block devices. It is no longer possible to open one BlueStore instance twice and the overwrite and corruption does not occur.
