034b91a3b6 [PATCH] v9fs: fix corner cases when flushing request
When v9fs_mux_rpc sends a 9P message, it may be put in the queue of unsent
request.  If the user process receives a signal, v9fs_mux_rpc sets the
request error to ERREQFLUSH and assigns NULL to request's send message.  If
the message was still in the unsent queue, v9fs_write_work would produce an
oops while processing it.

The patch makes sure that requests that are being flushed are moved to the
pending requests queue safely.

If a request is being flushed, don't remove it from the list of pending
requests even if it receives a reply before the flush is acknoledged.  The
request will be removed during from the Rflush handler (v9fs_mux_flush_cb).

23332c2e9d [PATCH] OProfile: fixed x86_64 incorrect kernel call graphs
Fix the problem in kernel 2.6.15.1 (and early versions) that OProfile on
x86_64 does not correctly collect the stack traces for kernel functions.

The original code in valid_kernel_stack() in arch/i386/oprofile/backtrace.c
assumes that the frame pointer (headaddr) should be greater than stack
(i.e., regs).

This assumption is wrong for x86_64 because NMIs in x86_64 use a seperate
stack different from the kernel stack.  Therefore, the variable stack now
points to some location on the NMI stack, which turns out to be at a higher
address than the frame pointer (headaddr) on the kernel stack.  The correct
comparison here should be between headaddr and regs->rsp for x86_64.

09114eb8c5 [PATCH] ufs: fix hang during `rm'
This fixes the code like this:

	bh = sb_find_get_block (sb, tmp + j);
	if ((bh && DATA_BUFFER_USED(bh)) || tmp != fs32_to_cpu(sb, *p)) {
		retry = 1;
		brelse (bh);
		goto next1;
	}
	bforget (bh);

sb_find_get_block() ordinarily returns a buffer_head with b_count>=2, and
this code assume that in case if "b_count>1" buffer is used, so this caused
infinite loop.

(akpm: that is-the-buffer-busy code is incomprehensible.  Good riddance.  Use
of block_truncate_page() seems sane).

e295cfcb29 [PATCH] ufs: fix oops with `ufs1' type
"rm" command, on file system with "ufs1" type cause system hang up.  This
is, in fact, not so bad as it seems to be, because of after that in "kernel
control path" there are 3-4 places which may cause "oops".

So the first patch fix oopses, and the second patch fix "kernel hang up".

"oops" appears because of reading of group's summary info partly wrong, and
access to not first group's summary info cause "oops".

54e8ce463a [PATCH] Tell kallsyms_lookup_name() to ignore type U entries
When one module exports a function symbol and another module uses that
symbol then kallsyms shows the symbol twice.  Once from the consumer with a
type of 'U' and once from the provider with a type of 't' or 'T'.  On most
architectures, both entries have the same address so it does not matter
which one is returned by kallsyms_lookup_name().  But on architectures with
function descriptors, the 'U' entry points to the descriptor, not to the
code body, which is not what we want.

IA64 # grep -w qla2x00_remove_one /proc/kallsyms
a000000208c25ef8 U qla2x00_remove_one   [qla2300]   <= descriptor

This patch is a cleanup/restructuring/clarification of the PCI error

278ff95370 [PATCH] Kprobes: Fix deadlock in function-return probes
When two function-return probes are inserted on kfree()[1] and the second
on say, sys_link()[2], and later [2] is unregistered, we have a deadlock as
kfree is called with the kretprobe_lock held and the function-return probe
on kfree will also try to grab the same lock.

However, we can move the kfree() during unregistration to outside the
spinlock as we are sure that no instances from the free list will be used
after synchronized_sched() returns during the unregistration process.
Thanks to Masami Hiramatsu for spotting this.

29fc7e3e70 [PATCH] md: Assorted little md fixes
- version-1 superblock
  + The default_bitmap_offset is in sectors, not bytes.
  + the 'size' field in the superblock is in sectors, not KB
- raid0_run should return a negative number on error, not '1'
- raid10_read_balance should not return a valid 'disk' number if
     ->rdev turned out to be NULL
- kmem_cache_destroy doesn't like being passed a NULL.

284ae7cab0 [PATCH] md: Handle overflow of mdu_array_info_t->size better
mdu_array_info_t->size is 'int', which isn't big enough for the size (in KB of
each component in) some arrays.

So rather than a random overflow, set size to -1 when it cannot be set
correctly.

To update aspect on an array, userspace will sometimes:
  get_array_info
  change one field
  set_array_info

in this case, we don't want the '-1' in 'size' to change to size, or look like
a size change at all.  So test for that in update_array_info.

ab11f89929 [PATCH] Clean up Documentation/driver-model/overview.txt
Edits to the driver-model documentation for grammar, clarity and content.

These docs haven't been updated in years, and some of the technical content
and discussion has become stale; this patch updates these.  In addition,
some of the language is awkward.  Fix this.

(I'm trying to cleanup the other files in this directory also,
patches for these will come a bit later).
