Pull VFS changes from Al Viro:
 "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"

DCACHE_DISCONNECTED) dentry is allocated and attached.
In the case of a directory, care is taken that only one dentry
can ever be attached.
d_splice_alias(inode, dentry) or d_materialise_unique(dentry, inode)
will introduce a new dentry into the tree; either the passed-in
dentry or a preexisting alias for the given inode (such as an
anonymous one created by d_obtain_alias), if appropriate. The two
functions differ in their handling of directories with preexisting
aliases:
d_splice_alias will use any existing IS_ROOT dentry, but it will
return -EIO rather than try to move a dentry with a different
parent. This is appropriate for local filesystems, which
should never see such an alias unless the filesystem is
corrupted somehow (for example, if two on-disk directory
entries refer to the same directory.)
d_materialise_unique will attempt to move any dentry. This is
appropriate for distributed filesystems, where finding a
directory other than where we last cached it may be a normal
consequence of concurrent operations on other hosts.
Both functions return NULL when the passed-in dentry is used,
following the calling convention of ->lookup.

been defined which make this task easy.
Most code will simply use seq_printf(), which works pretty much like
printk(), but which requires the seq_file pointer as an argument. It is
common to ignore the return value from seq_printf(), but a function
producing complicated output may want to check that value and quit if
something non-zero is returned; an error return means that the seq_file
buffer has been filled and further output will be discarded.
printk(), but which requires the seq_file pointer as an argument.
For straight character output, the following functions may be used:
int seq_putc(struct seq_file *m, char c);
int seq_puts(struct seq_file *m, const char *s);
int seq_escape(struct seq_file *m, const char *s, const char *esc);
seq_putc(struct seq_file *m, char c);
seq_puts(struct seq_file *m, const char *s);
seq_escape(struct seq_file *m, const char *s, const char *esc);
The first two output a single character and a string, just like one would
expect. seq_escape() is like seq_puts(), except that any character in s
which is in the string esc will be represented in octal form in the output.
There is also a pair of functions for printing filenames:

A function producing complicated output may want to check
bool seq_has_overflowed(struct seq_file *m);
and avoid further seq_<output> calls if true is returned.
A true return from seq_has_overflowed means that the seq_file buffer will
be discarded and the seq_show function will attempt to allocate a larger
buffer and retry printing.
