Don't put struct file on the stack as it takes up quite a lot of space
and violates lifetime rules for struct file.
Rather than calling afs_readpage() indirectly from the directory routines by
way of read_mapping_page(), split afs_readpage() to have afs_page_filler()
that's given a key instead of a file and call read_cache_page(), specifying the
new function directly. Use it in afs_readpages() as well.
Also make use of this in afs_mntpt_check_symlink() too for the same reason.

This is a seriously simplified patch from Eric Sandeen; copy of
rationale follows:
===
mounting stacked ecryptfs on ecryptfs has been shown to lead to bugs
in testing. For crypto info in xattr, there is no mechanism for handling
this at all, and for normal file headers, we run into other trouble:
BUG: unable to handle kernel NULL pointer dereference at 0000000000000008
IP: [<ffffffffa015b0b3>] ecryptfs_d_revalidate+0x43/0xa0 [ecryptfs]
...
There doesn't seem to be any good usecase for this, so I'd suggest just
disallowing the configuration.
Based on a patch originally, I believe, from Mike Halcrow.

The trace above is totally reproducible by doing a cross-directory
rename on an ecryptfs directory.
The issue seems to be that sys_renameat() does lock_rename() then calls
into the filesystem; if the filesystem is ecryptfs, then
ecryptfs_rename() again does lock_rename() on the lower filesystem, and
lockdep can't tell that the two s_vfs_rename_mutexes are different. It
seems an annotation like the following is sufficient to fix this (it
does get rid of the lockdep trace in my simple tests); however I would
like to make sure I'm not misunderstanding the locking, hence the CC
list...

ADDPART_FLAG_RAID was introduced in commit d18d768, and most places were
converted to use it instead of a hardcoded value. However, some places seem
to have been missed.
Change all of them to the symbolic names via the following semantic patch:
@@
struct parsed_partitions *state;
expression E;
@@
(
- state->parts[E].flags = 1
+ state->parts[E].flags = ADDPART_FLAG_RAID
|
- state->parts[E].flags |= 1
+ state->parts[E].flags |= ADDPART_FLAG_RAID
|
- state->parts[E].flags = 2
+ state->parts[E].flags = ADDPART_FLAG_WHOLEDISK
|
- state->parts[E].flags |= 2
+ state->parts[E].flags |= ADDPART_FLAG_WHOLEDISK

Now that the last user passing a NULL file pointer is gone we can remove
the redundant dentry argument and associated hacks inside vfs_fsynmc_range.
The next step will be removig the dentry argument from ->fsync, but given
the luck with the last round of method prototype changes I'd rather
defer this until after the main merge window.

Instead of just looking up a path use do_filp_open to get us a file
structure for the nfs4 recovery directory. This allows us to get
rid of the last non-standard vfs_fsync caller with a NULL file
pointer.

Using atomic_inc_return in __iget(struct inode *inode) makes the intent
of this code clearer and generates less code on processors that have
this operation.

anon_inode_mkinode() sets inode->i_mode = S_IRUSR | S_IWUSR; This means
that (inode->i_mode & S_IFMT) == 0. This trips up some SELinux code that
needs to determine if a given inode is a regular file, a directory, etc.
The easiest solution is to just make sure that the anon_inode also sets
S_IFREG.
