Subject: [PATCH] separate bdi congestion functions from queue congestion
 functions

Separate out the concept of "queue congestion" from "backing-dev congestion".
Congestion is a backing-dev concept, not a queue concept.

The blk_* congestion functions are retained, as wrappers around the core
backing-dev congestion functions.

This proper layering is needed so that NFS can cleanly use the congestion
functions, and so that CONFIG_BLOCK=n actually links.

Subject: [PATCH] fat: add fat_getattr()

This adds fat_getattr() for setting stat->blksize. (FAT uses the size
of cluster for proper I/O)
