When ext3_writepage races with truncate, block_write_full_page() will see
that the page is outside i_size and will bale out with -EIO.  But
ext3_writepage() will ignore this and will proceed to add the buffers to the
transaction.

Later, kjournald tries to write them out and goes BUG() because those buffers
are not mapped to disk.

The fix is to not attach the buffers to the transaction in ext3_writepage()
if block_write_full_page() failed.

So far so good, but that page now has dirty, unmapped buffers (the buffers
were attached in a dirty state by ext3_writepage()).  So teach
block_write_full_page() to clean the buffers against the page if it is wholly
outside i_size.

(A simpler fix to all of this mught be to just bale out of ext3_writepage()
if the page is outside i_size.  But that is racy against
block_write_full_page()'s subsequent execution of the same comparison).

Patch from: Oleg Drokin <green@namesys.com>

It moves all the arg checking code from the start of generic_file_aio_write()
into a standalone function, so other filesystems can avoid having to
cut-n-paste them.

The new function is exported to modules, and also inlined in filemap.c so
that the current filesystems are unaffected.  If someone is using ext2 and
reiserfs at the same time, they lose a bit of icache.

Patch from Oleg Drokin <green@namesys.com>

Move these already-inline functions to a header file so that filesystems can
reuse them.  For the reiserfs_file_write patch.

Considering that smp_call_function isn't allowed to hold a lock reference and
within smp_call_function we lock and unlock call_lock thus triggering a
preempt point.  Therefore we can't guarantee that we'll be on the same
processor when we hit do_flush_tlb_all_local.

void flush_tlb_all(void)
{
	smp_call_function (flush_tlb_all_ipi,0,1,1);

	do_flush_tlb_all_local();
}

...

smp_call_function()
{
	spin_lock(call_lock);
	...
	spin_unlock(call_lock);
	<preemption point>
}

...

do_flush_tlb_all_local() - possibly not executing on same processor
anymore.

I'm getting a build error:

	fs/jfs/super.c: In function `jfs_fill_super':
	fs/jfs/super.c:335: parse error before `)'

and it doesn't happen with gcc-3.2.x.

Taking out the file-n-line fixes it up.  This patch was acked by shaggy.

Robbie Williamson found some bugs in the mandatory locking implementation.
This patch fixes all the problems he found:

 - Fix null pointer dereference caused by sys_truncate() passing a null filp.
 - Honour the O_NONBLOCK flag when calling ftruncate()
 - Local variable `fl' wasn't being initialised correctly in
   locks_mandatory_area()
 - Don't return -ENOLCK from __posix_lock_file() when FL_ACCESS is set.

We must grab lock before checking rl->count.

bio-to-request front merging works, but request-to-request has been
broken due to a bit too much copy'n pasting.

Cleaner fix for the ioscheduler:

- Problem with alias request, the new request gets lost.
- Must always clear merge hash in move_to_dispatch()

Just approving this as maintainer of i2o_scsi

This lets me put mca-legacy into drivers to fix them for now without
worrying about losing the fact they want more attention

There are no known cards outside of labs that used i2o_lan. The only
exception is the Redcreek VPN, which has its own driver anyway. Note
i2o_lan.h is left as i2o_config can still understand i2o_lan devices
such as the RedCreek.

The following patches should fix those last two issues - compiling boot.c
for UP and compiling proc.c by default.

  This is needed because mark_buffer_dirty is now checking if buffer is up to date.
