Can't safely use uint32 for locker since we need to decrement the count, which requires loading the unit and doing some math, which is inherintly racey. Instead use Int32 which we can safely use with atomic and AddInt32 with `-1` Signed-off-by: Brian Goff <cpuguy83@gmail.com> Upstream-commit: 985175fd8f8f662d5067bd62a89330e9a437375c Component: engine
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!
