NFS: Ensure that rpc_release_resources_task() can be called twice.

BUG: atomic_dec_and_test(): -1: atomic counter underflow at:
Pid: 2827, comm: mount.nfs Not tainted 2.6.38 #1

Well, so, I think this is real bug of nfs codes somewhere. With some
review, the code

rpc_call_sync()
    rpc_run_task
        rpc_execute()
            __rpc_execute()
                rpc_release_task()
                    rpc_release_resources_task()
                        put_rpccred()                <= release cred
    rpc_put_task
        rpc_do_put_task()
            rpc_release_resources_task()
                put_rpccred()                        <= release cred again

seems to be release cred unintendedly.

NFS: Fix a hang in the writeback path

Now that the inode scalability patches have been merged, it is no longer
safe to call igrab() under the inode->i_lock.
Now that we no longer call nfs_clear_request() until the nfs_page is
being freed, we know that we are always holding a reference to the
nfs_open_context, which again holds a reference to the path, and so
the inode cannot be freed until the last nfs_page has been removed
from the radix tree and freed.

We can therefore skip the igrab()/iput() altogether.

system, due to the BIOS corrupting PMU state:

    Performance Events: PEBS fmt0+, Core2 events, Broken BIOS detected, using software events only.
    [Firmware Bug]: the BIOS has corrupted hw-PMU resources (MSR 186 is 43003c)

Linus suggested that we continue in the face of such BIOS-induced CPU
state corruption:

   http://lkml.org/lkml/2011/3/24/608

Such BIOSes will have to be fixed - Linux developers rely on a working and
fully capable PMU and the BIOS interfering with the CPU's PMU state is simply
not acceptable.

So this patch changes perf to continue when it detects such BIOS
interaction, some hardware events may be unreliable due to the BIOS
writing and re-writing them - there's not much the kernel can do
about that but to detect the corruption and report it.

On top of this file merge I have done a simplistic merge of m68k and

inode_lock from prune_icache and the initial part of iput_final().

instead of using the inode_lock to protect the inode during
iput_final, use the inode->i_lock instead. This protects the inode

inode while we are manipulating it. Hence we no longer need the
inode_lock in iput_final prior to setting I_FREEING on the inode.

For prune_icache, we no longer need the inode_lock to protect the
LRU list, and the inodes themselves are protected against freeing
races by the inode->i_lock. Hence we can lift the inode_lock from
prune_icache as well.

fs: Lock the inode LRU list separately

Introduce the inode_lru_lock to protect the inode_lru list. This
lock is nested inside the inode->i_lock to allow the inode to be
added to the LRU list in iput_final without needing to deal with
lock inversions. This keeps iput_final() clean and neat.

Further, where marking the inode I_FREEING and removing it from the
LRU, move the LRU list manipulation within the inode->i_lock to keep
the list manipulation consistent with iput_final. This also means
that most of the open coded LRU list removal + unused inode
accounting can now use the inode_lru_list_del() wrappers which
cleans the code up further.

However, this locking change means what the LRU traversal in
prune_icache() inverts this lock ordering and needs to use trylock
semantics on the inode->i_lock to avoid deadlocking. In these cases,
if we fail to lock the inode we move it to the back of the LRU to
prevent spinning on it.

fs: protect inode->i_state with inode->i_lock

Protect inode state transitions and validity checks with the

independently of the inode_lock and is the first step to peeling
away the inode_lock from the code.

This requires that __iget() is done atomically with i_state checks
during list traversals so that we don't race with another thread
marking the inode I_FREEING between the state check and grabbing the
reference.

Also remove the unlock_new_inode() memory barrier optimisation
required to avoid taking the inode_lock when clearing I_NEW.
Simplify the code by simply taking the inode->i_lock around the
state change and wakeup. Because the wakeup is no longer tricky,
remove the wake_up_inode() function and open code the wakeup where
necessary.
