24/* This needs enough for all file handles to have a buffer in the worst case
25 * plus at least one reserved exclusively for the cache client and a couple
26 * for other file system code. The buffers are put to use by the cache if not
27 * taken for another purpose (meaning nothing is wasted sitting fallow).
28 *
29 * One map per volume is maintained in order to avoid collisions between
30 * volumes that would slow cache probing. DC_MAP_NUM_ENTRIES is the number
31 * for each map per volume. The buffers themselves are shared.
