    list: add a new LRU list type · a38e4082
    Dave Chinner authored
    Several subsystems use the same construct for LRU lists - a list head, a
    spin lock and and item count.  They also use exactly the same code for
    adding and removing items from the LRU.  Create a generic type for these
    LRU lists.
    This is the beginning of generic, node aware LRUs for shrinkers to work
    [glommer@openvz.org: enum defined constants for lru. Suggested by gthelen, don't relock over retry]
