If rcu-walk mode we don't *have* to return -EISDIR for non-mount-traps
as we will simply drop into REF-walk and handling DCACHE_NEED_AUTOMOUNT
dentrys the slow way.  But it is better if we do when possible.

In 'oz_mode', use the same condition as ref-walk: if not a mountpoint,
then it must be -EISDIR.

In regular mode there are most tests needed.  Most of them can be
performed without taking any spinlocks.  If we find a directory that
isn't obviously empty, and isn't mounted on, we need to call
'simple_empty()' which does take a spinlock.  If this turned out to hurt
performance, some other approach could be found to signal when a
directory is known to be empty.

->fs_lock protects AUTOFS_INF_EXPIRING.  We need to be sure that once
the flag is set, no new references beneath the dentry are taken.  So
rcu-walk currently needs to take fs_lock before checking the flag.  This
hurts performance.

Change the expiry to a two-stage process.  First set AUTOFS_INF_NO_RCU
which forces any path walk into ref-walk mode, then drop the lock and
call synchronize_rcu().  Once that returns we can be sure no rcu-walk is
active beneath the dentry and we can check reference counts again.

Now during an RCU-walk we can test AUTOFS_INF_EXPIRING without taking
the lock as along as we test AUTOFS_INF_NO_RCU too.  If either are set,
we must abort the RCU-walk If neither are set, we know that refcounts
will be tested again after we finish the RCU-walk so we are safe to
continue.

->fs_lock is still taken in d_manage() to check for a non-trap
directory.  That will be resolved in the next patch.

This series teaches autofs about RCU-walk so that we don't drop straight
into REF-walk when we hit an autofs directory, and so that we avoid
spinlocks as much as possible when performing an RCU-walk.

This is needed so that the benefits of the recent NFS support for
RCU-walk are fully available when NFS filesystems are automounted.

Patches have been carefully reviewed and tested both with test suites
and in production - thanks a lot to Ian Kent for his support there.

This patch (of 6):

Any attempt to look up a pathname that passes though an autofs4 mount is
currently forced out of RCU-walk into REF-walk.

This can significantly hurt performance of many-thread work loads on
many-core systems, especially if the automounted filesystem supports
RCU-walk but doesn't get to benefit from it.

So if autofs4_d_manage is called with rcu_walk set, only fail with -ECHILD
if it is necessary to wait longer than a spinlock.

gcc-4.9 on ARM gives us a mysterious warning about the binfmt_misc
parse_command function:

  fs/binfmt_misc.c: In function 'parse_command.part.3':
  fs/binfmt_misc.c:405:7: warning: array subscript is above array bounds [-Warray-bounds]

I've managed to trace this back to the ARM implementation of memset,
which is called from copy_from_user in case of a fault and which does

 #define memset(p,v,n)                                                  \
        ({                                                              \
                void *__p = (p); size_t __n = n;                        \
                if ((__n) != 0) {                                       \
                        if (__builtin_constant_p((v)) && (v) == 0)      \
                                __memzero((__p),(__n));                 \
                        else                                            \
                                memset((__p),(v),(__n));                \
                }                                                       \
                (__p);                                                  \
        })

Apparently gcc gets confused by the check for "size != 0" and believes
that the size might be zero when it gets to the line that does "if
(s[count-1] == '\n')", so it would access data outside of the array.

gcc is clearly wrong here, since this condition was already checked
earlier in the function and the 'size' value can not change in the
meantime.

Fortunately, we can work around it and get rid of the warning by
rearranging the function to check for zero size after doing the
copy_from_user.  It is still safe to pass a zero size into
copy_from_user, so it does not cause any side effects.

The current code places a 256 byte limit on the registration format.
This ends up being fairly limited when you try to do matching against a
binary format like ELF:

 - the magic & mask formats cannot have any embedded NUL chars
   (string_unescape_inplace halts at the first NUL)
 - each escape sequence quadruples the size: \x00 is needed for NUL
 - trying to match bytes at the start of the file as well as further
   on leads to a lot of \x00 sequences in the mask
 - magic & mask have to be the same length (when decoded)
 - still need bytes for the other fields
 - impossible!

Let's look at a concrete (and common) example: using QEMU to run MIPS
ELFs.  The name field uses 11 bytes "qemu-mipsel".  The interp uses 20
bytes "/usr/bin/qemu-mipsel".  The type & flags takes up 4 bytes.  We
need 7 bytes for the delimiter (usually ":").  We can skip offset.  So
already we're down to 107 bytes to use with the magic/mask instead of
the real limit of 128 (BINPRM_BUF_SIZE).  If people use shell code to
register (which they do the majority of the time), they're down to ~26
possible bytes since the escape sequence must be \x##.

The ELF format looks like (both 32 & 64 bit):

	e_ident: 16 bytes
	e_type: 2 bytes
	e_machine: 2 bytes

Those 20 bytes are enough for most architectures because they have so few
formats in the first place, thus they can be uniquely identified.  That
also means for shell users, since 20 is smaller than 26, they can sanely
register a handler.

But for some targets (like MIPS), we need to poke further.  The ELF fields
continue on:

	e_entry: 4 or 8 bytes
	e_phoff: 4 or 8 bytes
	e_shoff: 4 or 8 bytes
	e_flags: 4 bytes

We only care about e_flags here as that includes the bits to identify
whether the ELF is O32/N32/N64.  But now we have to consume another 16
bytes (for 32 bit ELFs) or 28 bytes (for 64 bit ELFs) just to match the
flags.  If every byte is escaped, we send 288 more bytes to the kernel
((20 {e_ident,e_type,e_machine} + 12 {e_entry,e_phoff,e_shoff} + 4
{e_flags}) * 2 {mask,magic} * 4 {escape}) and we've clearly blown our
budget.

Even if we try to be clever and do the decoding ourselves (rather than
relying on the kernel to process \x##), we still can't hit the mark --
string_unescape_inplace treats mask & magic as C strings so NUL cannot
be embedded.  That leaves us with having to pass \x00 for the 12/24
entry/phoff/shoff bytes (as those will be completely random addresses),
and that is a minimum requirement of 48/96 bytes for the mask alone.
Add up the rest and we blow through it (this is for 64 bit ELFs):
magic: 20 {e_ident,e_type,e_machine} + 24 {e_entry,e_phoff,e_shoff} +
       4 {e_flags} = 48              # ^^ See note below.
mask: 20 {e_ident,e_type,e_machine} + 96 {e_entry,e_phoff,e_shoff} +
       4 {e_flags} = 120
Remember above we had 107 left over, and now we're at 168.  This is of
course the *best* case scenario -- you'll also want to have NUL bytes
in the magic & mask too to match literal zeros.

Note: the reason we can use 24 in the magic is that we can work off of the
fact that for bytes the mask would clobber, we can stuff any value into
magic that we want.  So when mask is \x00, we don't need the magic to also
be \x00, it can be an unescaped raw byte like '!'.  This lets us handle
more formats (barely) under the current 256 limit, but that's a pretty
tall hoop to force people to jump through.

With all that said, let's bump the limit from 256 bytes to 1920.  This way
we support escaping every byte of the mask & magic field (which is 1024
bytes by themselves -- 128 * 4 * 2), and we leave plenty of room for other
fields.  Like long paths to the interpreter (when you have source in your
/really/long/homedir/qemu/foo).  Since the current code stuffs more than
one structure into the same buffer, we leave a bit of space to easily
round up to 2k.  1920 is just as arbitrary as 256 ;).

The "_MODULE" suffix is reserved for tristates compiled as loadable kernel
modules (LKM).  The "TEST_MODULE" feature thereby violates this
convention.  The feature is used to compile the lib/test_module.c kernel
module.

Sadly this convention is not made explicit, but the Kconfig code documents
it.  The following code (./scripts/kconfig/confdata.c) is used to generate
the autoconf.h header file during the build process.  When a feature is
selected as a kernel module ('m'), it is suffixed with "_MODULE" to
indicate it.

	switch (*value) {
	case 'n':
		break;
	case 'm':
		suffix = "_MODULE";
		/* fall through */

This causes problems for static code analysis, which assumes a consistent
use of the "_MODULE" suffix.

This patch renames the feature and its reference in a Makefile to
"TEST_LKM", which still expresses the test of a LKM.

The prio_heap code is unused since commit 889ed9ce ("cgroup: remove
css_scan_tasks()").  It should be compiled out to shrink the binary
kernel size which can be done via introducing CONFIG_PRIO_HEAD or by
removing the code.

We can simply recover the code from git when needed, so it would be
better to remove it IMO.

Using seq_open_private() removes boilerplate code from ddebug_proc_open().

The resultant code is shorter and easier to follow.

This patch does not change any functionality.

Make the driver "Orphan" until he gets back with a working e-mail address

Commit 458df9fd ("printk: remove separate printk_sched buffers and use
printk buf instead") hardcodes printk_deferred() to KERN_WARNING and
inserts the string "[sched_delayed] " before the actual message.  However
it doesn't take into account the KERN_* prefix of the message, that now
ends up in the middle of the output:

 [sched_delayed] ^a4CE: hpet increased min_delta_ns to 20115 nsec

Fix this by just getting rid of the "[sched_delayed] " scnprintf().  The
prefix is useless since 458df9fd anyway since from that moment
printk_deferred() inserts the message into the kernel printk buffer
immediately.  So if the message eventually gets printed to console, it is
printed in the correct order with other messages and there's no need for
any special prefix.  And if the kernel crashes before the message makes it
to console, then prefix in the printk buffer doesn't make the situation
any better.
