Wong Source kernel commit: 90cfae818dac5227e94e21d0f5250e098432723e Move the btree buffer LRU refcount to the btree ops structure so that we can eliminate the last bc_btnum switch in the generic btree code. We're about to create repair-specific btree types, and we don't want that stuff cluttering up libxfs. Signed-off-by: Darrick J.
