Package nestedpendingoperations is a modified implementation of pkg/util/goroutinemap.

Package operationexecutor implements interfaces that enable execution of attach, detach, mount, and unmount operations with a nestedpendingoperations so that more than one operation is never triggered on the same volume for the same pod.

Package types defines types used only by volume components.

Package volumehelper contains consts and helper methods used by various volume components (attach/detach controller, kubelet, etc.).

FSInfo linux returns (available bytes, byte capacity, byte usage, error) for the filesystem that path resides upon.

IsReady checks for the existence of a regular file called 'ready' in the given directory and returns true if that file exists.

NewAtomicWriter creates a new AtomicWriter configured to write to the given target directory, or returns an error if the target directory does not exist.

NewDeviceHandler Create a new IoHandler implementation.

NewIOHandler Create a new IoHandler implementation.

PathExists returns true if the specified path exists.

SetReady creates a file called 'ready' in the given directory.

UnmountPath is a common unmount routine that unmounts the given path and deletes the remaining directory if successful.

AtomicWriter handles atomically projecting content for a set of files into a target directory.

DeviceUtil is a util for common device methods.

IoUtil is a mockable util for common IO operations.
