Using the new interval tree code we add a tree for each lock status list to efficiently track ranged requests. Internally, most operations on a resources lock status list (granted, waiting, converting) then are turned into operations within a given range. There is no API change other than a new call, dlm_lock_range() and a new structure, 'struct dlm_key' to define our range endpoints. Keys can have arbitrary lengths and are compared via memcmp. A ranged blocking ast type is defined so that users of dlm_lock_range() can know which range they are blocking. A rudimentary test, dlmtest.ko is included. TODO: - Update userspace entry points, need to add one for new lock call - Manage backwards compatibility with network protocol Signed-off-by: Mark Fasheh <mfasheh@versity.com>
