Attempt to address two performance issues:
1) The regression pointed out by Ben when doing 'ls -l' on a directory
that is being modified.
2) When using readdir() to iterate through a directory, avoid lookups
using the same method we use to avoid attribute revalidation.
The last patch is a cleanup.
Trond Myklebust (3):
NFS: Fix a performance regression in readdir
NFS: Be more targeted about readdirplus use when doing
lookup/revalidation
NFS: Replace nfs_force_use_readdirplus() with
nfs_advise_use_readdirplus()
