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
