Here is a refresh of my "remove congestion tracking" series.
It makes some small changes to readahead so that the effect of the
inode_read_congested() test in readahead can be duplicated in the
filesystem. fuse uses this.
It add some documentation for readahead, and for that to work, it
cleans up related doco a bit.
Andrew: please drop the version of this that is currently in your tree
even if you don't take this. The changes to fuse/nfs/ceph are not
appropriate.
Thanks,
NeilBrown
