[PATCH] taskstats: fix sub-threads accounting

If there are no listeners, taskstats_exit_send() just returns because
taskstats_exit_alloc() didn't allocate *tidstats.  This is wrong, each
sub-thread should do fill_tgid_exit() on exit, otherwise its ->delays is
not recorded in ->signal->stats and lost.

Q: We don't send TASKSTATS_TYPE_AGGR_TGID when single-threaded process
exits.  Is it good?  How can the listener figure out that it was actually a
process exit, not sub-thread?

[PATCH] uml ubd driver: ubd_io_lock usage fixup

Add some comments about requirements for ubd_io_lock and expand its use.

When an irq signals that the "controller" (i.e.  another thread on the host,
which does the actual requests and is the only one blocked on I/O on the host)
has done some work, we call again the request function ourselves
(do_ubd_request).

We now do that with ubd_io_lock held - that's useful to protect against
concurrent calls to elv_next_request and so on.

XXX: Maybe we shouldn't call at all the request function.  Input needed on
this.  Are we supposed to plug and unplug the queue?  That code "indirectly"
does that by setting a flag, called do_ubd, which makes the request function
return (it's a residual of 2.4 block layer interface).

Meanwhile, however, merge this patch, which improves things.

[PATCH] uml ubd driver: change ubd_lock to be a mutex

This lock protects ubd setup and teardown, so is only used in process context;
beyond that, during such setup memory allocations must be performed and some
generic functions which can sleep must be called (such as add_disk()).  So the
only correct solution is to make it a mutex instead of a spin_lock.  No other

[PATCH] clean up add_bd_holder()

add_bd_holder() is called from bd_claim_by_kobject to put a given struct
bd_holder in the list if there is no matching entry.

There are 3 possible results of add_bd_holder():
  1. there is no matching entry and add the given one to the list
  2. there is matching entry, so just increment reference count of
     the existing one
  3. something failed during its course

1 and 2 are successful cases.  But for case 2, someone has to free the
unused struct bd_holder.

The current code frees it inside of add_bd_holder and returns same value
0 for both cases 1 and 2.  However, it's natural and less error-prone if
caller frees it since it's allocated by the caller.

[PATCH] sunrpc: fix refcounting problems in rpc servers

A recent patch fixed a problem which would occur when the refcount on an
auth_domain reached zero.  This problem has not been reported in practice
despite existing in two major kernel releases because the refcount can
never reach zero.

This patch fixes the problems that stop the refcount reaching zero.

1/ We were adding to the refcount when inserting in the hash table,
   but only removing from the hashtable when the refcount reached zero.
   Obviously it never would.  So don't count the implied reference of
   being in the hash table.

2/ There are two paths on which a socket can be destroyed.  One called
   svcauth_unix_info_release().  The other didn't.  So when the other was
   taken, we can lose a reference to an ip_map which in-turn holds a
   reference to an auth_domain

   So unify the exit paths into svc_sock_put.  This highlights the fact
   that svc_delete_socket has slightly odd semantics - it does not drop
   a reference but probably should.  Fixing this need a bit more
   thought and testing.

Revert "r8169: mac address change support"

This reverts commit a2b98a697fa4e7564f78905b83db122824916cf9.

As per Guennadi Liakhovetski, the mac address change support code breaks
some normal uses (_without_ any address changes), and until it's all
sorted out, we're better off without it.

Says Francois:

  "Go revert it.

   Despite what I claimed, I can not find a third-party confirmation by
   email that it works elsewhere.

   It would probably be enough to remove the call to
   __rtl8169_set_mac_addr() in rtl8169_hw_start() though."

[PATCH] Fix GFP_HIGHMEM slab panic

As reported by Martin J. Bligh <mbligh@google.com>, we let through some
non-slab bits to slab allocation through __get_vm_area_node when doing a
vmalloc.

I haven't been able to reproduce this, although I understand why it
happens: vmalloc allocates memory with

GFP_KERNEL | __GFP_HIGHMEM

and commit 52fd24ca1db3a741f144bbc229beefe044202cac resulted in the same
flags are passed down to cache_alloc_refill, causing the BUG.  The
following patch fixes it.

Note that when calling kmalloc_node, I am masking off __GFP_HIGHMEM with
GFP_LEVEL_MASK, whereas __vmalloc_area_node does the same with

~(__GFP_HIGHMEM | __GFP_ZERO).

IMHO, using GFP_LEVEL_MASK is preferable, but either should fix this
problem.

[PATCH] Calculation fix for memory holes beyong the end of physical memory

absent_pages_in_range() made the assumption that users of the
arch-independent zone-sizing API would not care about holes beyound the end
of physical memory.  This was not the case and was "fixed" in a patch
called "Account for holes that are outside the range of physical memory".
However, when given a range that started before a hole in "real" memory and
ended beyond the end of memory, it would get the result wrong.  The bug is
in mainline but a patch is below.

It has been tested successfully on a number of machines and architectures.

   tsk->parent never == NULL, and it is unsafe to dereference it.
   Both the task and it's parent may exit after the caller unlocks

[PATCH] fill_tgid: fix task_struct leak and possible oops

1. fill_tgid() forgets to do put_task_struct(first).

2. release_task(first) can happen after fill_tgid() drops tasklist_lock,
   it is unsafe to dereference first->signal.

This is a temporary fix, imho the locking should be reworked.

[PATCH] strstrip remove last blank fix

strstrip() does not remove the last blank from strings which only consist
of blanks.

Example:
char string[] = "  ";
strstrip(string);

results in " ", but should produce an empty string!

[PATCH] missing unused dentry in prune_dcache()?

On the the following patch:
http://linux.bkbits.net:8080/linux-2.6/gnupatch@449b144ecSF1rYskg3q-SeR2vf88zg

# ChangeSet
#   2006/06/22 15:05:57-07:00 neilb@suse.de
#   [PATCH] Fix dcache race during umount

#   If prune_dcache finds a dentry that it cannot free, it leaves it where it
#   is (at the tail of the list) and exits, on the assumption that some other
#   thread will be removing that dentry soon.

However as far as I see this comment is not correct: when we cannot take
s_umount rw_semaphore (for example because it was taken in do_remount) this
dentry is already extracted from dentry_unused list and we do not add it
into the list again.  Therefore dentry will not be found by prune_dcache()
and shrink_dcache_sb() and will leave in memory very long time until the
partition will be unmounted.

The patch adds this dentry into tail of the dentry_unused list.

[PATCH] hugetlb: fix prio_tree unit

hugetlb_vmtruncate_list was misconverted to prio_tree: its prio_tree is in
units of PAGE_SIZE (PAGE_CACHE_SIZE) like any other, not HPAGE_SIZE (whereas
its radix_tree is kept in units of HPAGE_SIZE, otherwise slots would be
absurdly sparse).

At first I thought the error benign, just calling __unmap_hugepage_range on
more vmas than necessary; but on 32-bit machines, when the prio_tree is
searched correctly, it happens to ensure the v_offset calculation won't
overflow.  As it stood, when truncating at or beyond 4GB, it was liable to
discard pages COWed from lower offsets; or even to clear pmd entries of
preceding vmas, triggering exit_mmap's BUG_ON(nr_ptes).

On 32-bit machines, mount -t hugetlbfs -o size=4G gave a 0GB filesystem,

[PATCH] __vmalloc with GFP_ATOMIC causes 'sleeping from invalid context'

If __vmalloc is called to allocate memory with GFP_ATOMIC in atomic
context, the chain of calls results in __get_vm_area_node allocating memory
for vm_struct with GFP_KERNEL, causing the 'sleeping from invalid context'
warning.  This patch fixes it by passing the gfp flags along so
__get_vm_area_node allocates memory for vm_struct with the same flags.

[PATCH] memory hotplug: __GFP_NOWARN is better for __kmalloc_section_memmap()

Add __GFP_NOWARN flag to calling of __alloc_pages() in
__kmalloc_section_memmap().  It can reduce noisy failure message.

In ia64, section size is 1 GB, this means that order 8 pages are necessary
for each section's memmap.  It is often very hard requirement under heavy
memory pressure as you know.  So, __alloc_pages() gives up allocation and
shows many noisy stack traces which means no page for each sections.
(Current my environment shows 32 times of stack trace....)

But, __kmalloc_section_memmap() calls vmalloc() after failure of it, and it
can succeed allocation of memmap.  So, its stack trace warning becomes just
noisy.  I suppose it shouldn't be shown.
