/**
* This file contains implementation of PLAIN lock type.
*
* PLAIN locks are the simplest form of LDLM locking, and are used when
* there only needs to be a single lock on a resource. This avoids some
* of the complexity of EXTENT and IBITS lock types, but doesn't allow
* different "parts" of a resource to be locked concurrently. Example
* use cases for PLAIN locks include locking of MGS configuration logs
* and (as of Lustre 2.4) quota records.
