Synopsis:
#include <fs_crypto_api.h>

Arguments:
- path
- The path to the filesystem's mountpoint.

specified client data from the whitelist for the specified domain. The result is the client will
be revoked access from the domain when a hard lock is pending.
- type
- The type of whitelist to carry out the action on. Must be one of the following:
- FS_CRYPTO_WHITELIST_TYPE_PID — process ID.
- FS_CRYPTO_WHITELIST_TYPE_GID — group ID.
