da6c28aaf62fa55f0fdb8004aa40f88f23bf53f0amw * --------
da6c28aaf62fa55f0fdb8004aa40f88f23bf53f0amw *
da6c28aaf62fa55f0fdb8004aa40f88f23bf53f0amw *    The state machine of the tree structures is controlled by 3 elements:
da6c28aaf62fa55f0fdb8004aa40f88f23bf53f0amw *      - The list of trees of the user it belongs to.
da6c28aaf62fa55f0fdb8004aa40f88f23bf53f0amw *      - The mutex embedded in the structure itself.
da6c28aaf62fa55f0fdb8004aa40f88f23bf53f0amw *      - The reference count.
da6c28aaf62fa55f0fdb8004aa40f88f23bf53f0amw *
da6c28aaf62fa55f0fdb8004aa40f88f23bf53f0amw *    There's a mutex embedded in the tree structure used to protect its fields
da6c28aaf62fa55f0fdb8004aa40f88f23bf53f0amw *    and there's a lock embedded in the list of trees of a user. To
da6c28aaf62fa55f0fdb8004aa40f88f23bf53f0amw *    increment or to decrement the reference count the mutex must be entered.
da6c28aaf62fa55f0fdb8004aa40f88f23bf53f0amw *    To insert the tree into the list of trees of the user and to remove
da6c28aaf62fa55f0fdb8004aa40f88f23bf53f0amw *    the tree from it, the lock must be entered in RW_WRITER mode.
da6c28aaf62fa55f0fdb8004aa40f88f23bf53f0amw *
da6c28aaf62fa55f0fdb8004aa40f88f23bf53f0amw *    Rules of access to a tree structure:
da6c28aaf62fa55f0fdb8004aa40f88f23bf53f0amw *
da6c28aaf62fa55f0fdb8004aa40f88f23bf53f0amw *    1) In order to avoid deadlocks, when both (mutex and lock of the user
da6c28aaf62fa55f0fdb8004aa40f88f23bf53f0amw *       list) have to be entered, the lock must be entered first.
da6c28aaf62fa55f0fdb8004aa40f88f23bf53f0amw *
da6c28aaf62fa55f0fdb8004aa40f88f23bf53f0amw *    2) All actions applied to a tree require a reference count.
da6c28aaf62fa55f0fdb8004aa40f88f23bf53f0amw *
c8ec8eea9849cac239663c46be8a7f5d2ba7ca00jose borrego *    3) There are 2 ways of getting a reference count: when a tree is
c8ec8eea9849cac239663c46be8a7f5d2ba7ca00jose borrego *       connected and when a tree is looked up.
da6c28aaf62fa55f0fdb8004aa40f88f23bf53f0amw *
da6c28aaf62fa55f0fdb8004aa40f88f23bf53f0amw *    It should be noted that the reference count of a tree registers the
da6c28aaf62fa55f0fdb8004aa40f88f23bf53f0amw *    number of references to the tree in other structures (such as an smb
da6c28aaf62fa55f0fdb8004aa40f88f23bf53f0amw *    request). The reference count is not incremented in these 2 instances:
da6c28aaf62fa55f0fdb8004aa40f88f23bf53f0amw *
da6c28aaf62fa55f0fdb8004aa40f88f23bf53f0amw *    1) The tree is connected. An tree is anchored by his state. If there's
da6c28aaf62fa55f0fdb8004aa40f88f23bf53f0amw *       no activity involving a tree currently connected, the reference
da6c28aaf62fa55f0fdb8004aa40f88f23bf53f0amw *       count of that tree is zero.
da6c28aaf62fa55f0fdb8004aa40f88f23bf53f0amw *
da6c28aaf62fa55f0fdb8004aa40f88f23bf53f0amw *    2) The tree is queued in the list of trees of the user. The fact of
da6c28aaf62fa55f0fdb8004aa40f88f23bf53f0amw *       being queued in that list is NOT registered by incrementing the
da6c28aaf62fa55f0fdb8004aa40f88f23bf53f0amw *       reference count.
