[PATCH] qla2xxx: cleanup DMA mappings...

  Don't use cmd->request->nr_hw_segments as it may not be initialized
  (SG_IO in particular bypasses anything that initializes this and just
  uses scsi_do_req to insert a scsi_request directly on the head of the
  queue) and a bogus value here can trip up the checks to make sure that
  the number of segments will fit in the queue ring buffer, resulting in
  commands that are never completed.

  Fix up several issues with PCI DMA mapping and failure to check return
  values on the mappings.

  Make the check for space in the ring buffer happen after the DMA mapping
  is done since any checks done before the mapping has taken place are
  bogus.

[PATCH] jbd dirty buffer leak fix

This fixes the lots-of-fsx-linux-instances-cause-a-slow-leak bug.

It's been there since 2.6.6, caused by:

ftp://ftp.kernel.org/pub/linux/kernel/people/akpm/patches/2.6/2.6.5/2.6.5-mm4/broken-out/jbd-move-locked-buffers.patch

That patch moves under-writeout ordered-data buffers onto a separate journal
list during commit.  It took out the old code which was based on a single
list.

The old code (necessarily) had logic which would restart I/O against buffers
which had been redirtied while they were on the committing transaction's
t_sync_datalist list.  The new code only writes buffers once, ignoring
redirtyings by a later transaction, which is good.

But over on the truncate side of things, in journal_unmap_buffer(), we're
treating buffers on the t_locked_list as inviolable things which belong to the
committing transaction, and we just leave them alone during concurrent
truncate-vs-commit.

The net effect is that when truncate tries to invalidate a page whose buffers
are on t_locked_list and have been redirtied, journal_unmap_buffer() just
leaves those buffers alone.  truncate will remove the page from its mapping
and we end up with an anonymous clean page with dirty buffers, which is an
illegal state for a page.  The JBD commit will not clean those buffers as they
are removed from t_locked_list.  The VM (try_to_free_buffers) cannot reclaim
these pages.

The patch teaches journal_unmap_buffer() about buffers which are on the
committing transaction's t_locked_list.  These buffers have been written and
I/O has completed.  We can take them off the transaction and undirty them
within the context of journal_invalidatepage()->journal_unmap_buffer().

[PATCH] IB/mthca: fix MTT allocation in mem-free mode

Fix bug in MTT allocation in mem-free mode.

I misunderstood the MTT size value returned by the firmware -- it is really
the size of a single MTT entry, since mem-free mode does not segment the MTT
as the original firmware did.  This meant that our MTT addresses ended up
being off by a factor of 8.  This meant that our MTT allocations might
overlap, and so we could overwrite and corrupt earlier memory regions when
writing new MTT entries.

We fix this by always using our 64-byte MTT segment size.  This allows some
simplification of the code as well, since there's no reason to put the MTT
segment size in a variable -- we can always use our enum value directly.

[PATCH] add Big Endian variants of ioread/iowrite

In the new io infrastructure, all of our operators are expecting the
underlying device to be little endian (because the PCI bus, their main
consumer, is LE).

However, there are a fair few devices and busses in the world that are
actually Big Endian.  There's even evidence that some of these BE bus and
chip types are attached to LE systems.  Thus, there's a need for a BE
equivalent of our io{read,write}{16,32} operations.

The attached patch adds this as io{read,write}{16,32}be.  When it's in,
I'll add the first consume (the 53c700 SCSI chip driver).

The direct I/O code is mapping the read request to the file system block.  If

file size if the read reads past EOF.

When I/O completes the result can be truncated to match the file size
without using i_size_read(), thus the aio result now matches the number of
bytes read to the end of file.

[PATCH] ext2 corruption - regression between 2.6.9 and 2.6.10

Whilst trying to stress test a Promise SX8 card, we stumbled across
some nasty filesystem corruption in ext2. Our tests involved
creating an ext2 partition, mounting, running several concurrent
fsx's over it, umounting, and fsck'ing, all scripted[1]. The fsck
would always return with errors.

This regression was traced back to a change between 2.6.9 and
2.6.10, which moves the functionality of ext2_put_inode into
ext2_clear_inode.  The attached patch reverses this change, and
eliminated the source of corruption.

Mingming Cao <cmm@us.ibm.com> said:

I think his patch for ext2 is correct.  The corruption on ext3 is not the same
issue he saw on ext2.  I believe that's the race between discard reservation
and reservation in-use that we already fixed it in 2.6.12- rc1.

For the problem related to ext2, at the time when we design reservation for
ext3, we decide we only need to discard the reservation at the last file
close, so we have ext3_discard_reservation on iput_final- >ext3_clear_inode.

The ext2 handle discard preallocation differently at that time, it discard the
preallocation at each iput(), not in input_final(), so we think it's
unnecessary to thrash it so frequently, and the right thing to do, as we did
for ext3 reservation, discard preallocation on last iput().  So we moved the
ext2_discard_preallocation from ext2_put_inode(0 to ext2_clear_inode.

Since ext2 preallocation is doing pre-allocation on disk, so it is possible
that at the unmount time, someone is still hold the reference of the inode, so
the preallocation for a file is not discard yet, so we still mark those blocks
allocated on disk, while they are not actually in the inode's block map, so
fsck will catch/fix that error later.

This is not a issue for ext3, as ext3 reservation(pre-allocation) is done in
memory.

still a totally useless layer of function pointer indirections, but maybe
someone else will fix that bit up.

[PATCH] use cheaper elv_queue_empty when unplug a device

In function __generic_unplug_device(), kernel can use a cheaper function
elv_queue_empty() instead of more expensive elv_next_request to find
whether the queue is empty or not.  blk_run_queue can also made conditional
on whether queue's emptiness before calling request_fn().

[PATCH] fix module_param_string() calls

This patch fix 3 calls to module_param_string() in
driver/media/video/tuner-core.c and drivers/media/video/tda9887.c.  In all
three places, the len and the perm parameter was switched.

[PATCH] kernel/param.c: don't use .max when .num is NULL in param_array_set()

there seems to be a bug, at least for me, in kernel/param.c for arrays with
.num == NULL.  If .num == NULL, the function param_array_set() uses &.max
for the call to param_array(), wich alters the .max value to the number of
arguments.  The result is, you can't set more array arguments as the last
time you set the parameter.

example:

# a module 'example' with
# static int array[10] = { 0, };
# module_param_array(array, int, NULL, 0644);

$ insmod example.ko array=1,2,3
$ cat /sys/module/example/parameters/array
1,2,3
$ echo "4,3,2,1" > /sys/module/example/parameters/array
$ dmesg | tail -n 1
kernel: array: can take only 3 arguments

[PATCH] AYSNC IO using singals other than SIGIO

A question on sigwaitinfo based IO mechanism in multithreaded applications.

I am trying to use RT signals to notify me of IO events using RT signals
instead of SIGIO in a multithreaded applications.  I noticed that there was
some discussion on lkml during november 1999 with the subject of the
discussion as "Signal driven IO".  In the thread I noticed that RT signals
were being delivered to the worker thread.  I am running 2.6.10 kernel and
I am trying to use the very same mechanism and I find that only SIGIO being
propogated to the worker threads and RT signals only being propogated to
the main thread and not the worker threads where I actually want them to be
propogated too.  On further inspection I found that the following patch
which I have attached solves the problem.

I am not sure if this is a bug or feature in the kernel.

Roland McGrath <roland@redhat.com> said:

This relates only to fcntl F_SETSIG, which is a Linux extension.  So there is
no POSIX issue.  When changing various things like the normal SIGIO signalling
to do group signals, I was concerned strictly with the POSIX semantics and
generally avoided touching things in the domain of Linux inventions.  That's
why I didn't change this when I changed the call right next to it.  There is
no reason I can see that F_SETSIG-requested signals shouldn't use a group
signal like normal SIGIO does.  I'm happy to ACK this patch, there is nothing
wrong with its change to the semantics in my book.  But neither POSIX nor I
care a whit what F_SETSIG does.
