if there is no cookie set in dm task, or flag DM_UDEV_DISABLE_LIBRARY_FALLBACK is cleared for a DM_DEV_REMOVE task, libdevmapper will fallback to clean up the symlink under /dev/mapper by itself, no matter the device removal is executed immediately or deferred by the kernel.In some cases, the removal is deferred by the kernel, while the symlink is deleted directly by libdevmapper, when docker tries to activate the device again, the deferred removal will be canceld, but the symlink will not show up again, so docker's attempt to mount the device by the symlink will fail, and it will eventually leads to a `docker start/diff` error.

pkg/ is a collection of utility packages used by the Docker project without being specific to its internals.
Utility packages are kept separate from the docker core codebase to keep it as small and concise as possible. If some utilities grow larger and their APIs stabilize, they may be moved to their own repository under the Docker organization, to facilitate re-use by other projects. However that is not the priority.
The directory pkg is named after the same directory in the camlistore project. Since Brad is a core
Go maintainer, we thought it made sense to copy his methods for organizing Go code :) Thanks Brad!
Because utility packages are small and neatly separated from the rest of the codebase, they are a good place to start for aspiring maintainers and contributors. Get in touch if you want to help maintain them!
