/*
 * LIBEFC LOCKING
 *
 * The critical sections protected by the efc's spinlock are quite broad and
 * may be improved upon in the future. The libefc code and its locking doesn't
 * influence the I/O path, so excessive locking doesn't impact I/O performance.
 *
 * The strategy is to lock whenever processing a request from user driver. This
 * means that the entry points into the libefc library are protected by efc
 * lock. So all the state machine transitions are protected.
