First pile out of several (there _definitely_ will be more). Stuff in this
one:
* unification of d_splice_alias()/d_materialize_unique()
* iov_iter rewrite
* killing a bunch of ->f_path.dentry users (and f_dentry macro).
Getting that completed will make life much simpler for unionmount/overlayfs,
since then we'll be able to limit the places sensitive to file _dentry_
to reasonably few. Which allows to have file_inode(file) pointing to
inode in a covered layer, with dentry pointing to (negative) dentry in
union one. Still not complete, but much closer now.
* crapectomy in lustre (dead code removal, mostly)
* "let's make seq_printf return nothing" preparations
* assorted cleanups and fixes
There _definitely_ will be more piles. Please, pull from

Shortlog:
Al Viro (53):
new helper: is_root_inode()
move d_rcu from overlapping d_child to overlapping d_alias
lustre: switch ll_intent_file_open() to struct dentry *
ll_setxattr(): get rid of struct file on stack
lustre: opened file can't have negative dentry
lustre: use %p[dD]
lustre: use file_inode()
lustre: switch ll_release_openhandle() to struct inode *
kill ll_mknod_generic()
kill ll_mkdir_generic()
kill ll_symlink_generic()
ll_new_inode(): don't bother with name - it's always &dentry->d_name
kill ll_rmdir_generic()
kill ll_unlink_generic()
kill ll_rename_generic()
ll_get_child_fid(): callers already have the child
kill ll_link_generic()
lustre: get rid of duplicate mountpoint checks
lustre: use is_root_inode()
deal with deadlock in d_walk()
gfs2: bugger off early if O_CREAT open finds a directory
gfs2_create_inode(): don't bother with d_splice_alias()
gfs2_atomic_open(): simplify the use of finish_no_open()
d_add_ci() should just accept a hashed exact match if it finds one
merge d_materialise_unique() into d_splice_alias()
switch d_materialise_unique() users to d_splice_alias()
assorted conversions to %p[dD]
