Currently exfat_map_cluster() allocates and returns only one cluster at a time even when more clusters are needed. This causes multiple FAT walks and repeated allocation calls during large sequential writes or when using iomap for writes. This change exfat_map_cluster() and exfat_alloc_cluster() to be able to allocate multiple contiguous clusters. Acked-by: Christoph Hellwig <hch@lst.de> Acked-by: "Darrick J.
