[PATCH 24/32] afs: Use new fscache read helper API

Make AFS use the new fscache read helpers to implement the VM read operations: - afs_readpage() now hands off responsibility to fscache_readpage(). - afs_readpages() is gone and replaced with afs_readahead(). - afs_readahead() just hands off responsibility to fscache_readahead(). These make

[PATCH 23/32] afs: Use the fs operation ops to handle FetchData completion

[PATCH 26/32] NFS: In nfs_readpage() only increment NFSIOS_READPAGES when read succeeds

From: Dave Wysochanski There is a small inconsistency with nfs_readpage() vs nfs_readpages() with regards to NFSIOS_READPAGES. In readpage we unconditionally increment NFSIOS_READPAGES at the top, which means even if the read fails. In readpages, we increment NFSIOS_READPAGES at the bottom base
