Merge branch 'dentry-cleanups' (dcache access cleanups and optimizations)
This branch simplifies and clarifies the dcache lookup, and allows us to
do certain nice optimizations when comparing dentries. It also cleans
up the interface to __d_lookup_rcu(), especially around passing the
inode information around.
* dentry-cleanups:
vfs: make it possible to access the dentry hash/len as one 64-bit entry
vfs: move dentry name length comparison from dentry_cmp() into callers
vfs: do the careful dentry name access for all dentry_cmp cases
vfs: remove unnecessary d_unhashed() check from __d_lookup_rcu
vfs: clean up __d_lookup_rcu() and dentry_cmp() interfaces
