// FindGlobalMapPathUUIDFromPod finds {pod uuid} bind mount under globalMapPath

func (v VolumePathHandler) FindGlobalMapPathUUIDFromPod(pluginDir, mapPath string, podUID types.UID) (string, error) {

Mapping and unmapping of a device in a publish path to its global map path and its
pod device map path are done by operation_executor through MapBlockVolume/UnmapBlockVolume
(MapBlockVolume and UnmapBlockVolume take care for lock, symlink, and bind mount).

Summary of block volume related CSI driver's methods are as follows:
 - GetGlobalMapPath returns a global map path,
 - GetPodDeviceMapPath returns a pod device map path and filename,

// buildImportcfgSymlinks builds in root a tree of symlinks
// implementing the directives from importcfg.
// This serves as a temporary transition mechanism until
// we can depend on gccgo reading an importcfg directly.
// (The Go 1.9 and later gc compilers already do.)

# Usage: setup_venv_test.sh venv_and_symlink_name "glob pattern for one wheel file"
# Example: setup_venv_test.sh bazel_pip "/tf/pkg/*.whl"
# 
# This will create a venv with that wheel file installed in it, and a symlink
# in ./venv_and_symlink_name/tensorflow to ./tensorflow. We use this for the
# "pip" tests.

python -m venv /$1
mkdir -p $1
rm -f ./$1/tensorflow
ln -s $(ls /$1/lib) /$1/lib/python3

stop [msg]
	stop execution of the script

	The message is written to the script log, but no error is
	reported from the script engine.

symlink path -> target
	create a symlink

	Creates path as a symlink to target.
	The '->' token (like in 'ls -l' output on Unix) is required.

wait 
	wait for completion of background commands

	Waits for all background commands to complete.
