While busy-waiting for completion, check the hardware after scheduling;
don't schedule and then immediately check the _timeout_. If the yield()
took a long time (as it does on my OLPC prototype board when it's busy),
we'd report a timeout even though the hardware was now ready.This fixes it, and also switches the yield() for a cond_resched() because
we don't actually want to be _that_ nice about it. I see nice
tightly-packed SMBus transactions now, rather than waiting for milliseconds
between successive phases.Actually, we shouldn't be busy-waiting here at all. We should be using
interrupts. That's an exercise for another day though.Signed-off-by: David Woodhouse

I saw an oops down this path when trying to create a new file on a UDF
filesystem which was internally marked as readonly, but mounted rw:udf_create
udf_new_inode
new_inode
alloc_inode
udf_alloc_inode
udf_new_block
returns EIO due to readonlyness
iput (on error)
udf_put_inode
udf_discard_prealloc
udf_next_aext
udf_current_aext
udf_get_fileshortad
OOPSthe udf_discard_prealloc() path was examining uninitialized fields of the
udf inode.udf_discard_prealloc() already has this code to short-circuit the discard
path if no extents are preallocated:if (UDF_I_ALLOCTYPE(inode) == ICBTAG_FLAG_AD_IN_ICB ||
inode->i_size == UDF_I_LENEXTENTS(inode))
{
return;
}so if we initialize UDF_I_LENEXTENTS(inode) = 0 earlier in udf_new_inode,
we won't try to free the (not) preallocated blocks, since this will match
the i_size = 0 set when the inode was initialized.Signed-off-by: Eric Sandeen

A patch in -mm kernel correct the parsing of "address resources" of pnpacpi.
Before we assumed it was memory only, but it could be also IO.But this change show an hidden bug : some resources could be producer type
that are not handled by pnp layer. So we should ignore the producer
resources.This patch fixes bug 6292 (http://bugzilla.kernel.org/show_bug.cgi?id=6292).
Some devices like PNP0A03 have 0xd00-0xffff and 0x0-0xcf7 as IO producer
resources.Before correcting "address resources" parsing, it was seen as memory and was
harmless, because nobody tried to reserve this memory range as it should be
IO.With the correction it become IO resources, and make failed all others device
that want to register IO in this range and use pnp layer (like a ISA sound
card).The solution is to ignore producer resources

reiserfs_write_full_page does zero bytes in the file past eof, but it may
call get_block on those buffers as well. On machines where the page size
is larger than the blocksize, this can result in mmaped files incorrectly
growing up to a block boundary during writepage.The fix is to avoid calling get_block for any blocks that are entirely past

This patch is for collision check enhancement for memory hot add.
It's better to do resouce collision check before doing memory hot add,
which will touch memory management structures.And add_section() should check section exists or not before calling
sparse_add_one_section(). (sparse_add_one_section() will do another
check anyway. but checking in memory_hotplug.c will be easy to understand.)Signed-off-by: KAMEZAWA Hiroyuki

add_memory() does all necessary check to avoid collision. then, acpi layer
doesn't have to check region by itself.(*) pfn_valid() just returns page struct is valid or not. It returns 0

ioresouce handling code in memory hotplug allows not-aligned memory hot add.
But when memmap and other memory structures are initialized, parameters should

assumes parameters are aligned.) This patch fix it.And this patch allows ioresource collision check to handle -EEXIST.

In bugzilla #6941, Jens Kilian reported:
"The function befs_utf2nls (in fs/befs/linuxvfs.c) writes a 0 byte past the
end of a block of memory allocated via kmalloc(), leading to memory
corruption. This happens only for filenames which are pure ASCII and a
multiple of 4 bytes in length. [...]Without DEBUG_SLAB, this leads to further corruption and hard lockups; I
believe this is the bug which has made kernels later than 2.6.8 unusable
for me. (This must be due to changes in memory management, the bug has
been in the BeFS driver since the time it was introduced (AFAICT).)Steps to reproduce:
Create a directory (in BeOS, naturally :-) with files named, e.g.,
"1", "22", "333", "4444", ... Mount it in Linux and do an "ls" or "find""This patch implements the suggested fix. Credits to Jens Kilian for

If we don't find the item we are lookng for, we allocate a new one, and
then grab the lock again and search to see if it has been added while we
did the alloc. If it had been added we need to 'cache_put' the newly
created item that we are never going to use. But as it hasn't been
initialised properly, putting it can cause an oops.So move the ->init call earlier to that it will always be fully initilised
if we have to put it.Thanks to Philipp Matthias Hahn

The POSIX_FADV_NOREUSE hint means "the application will use this range of the
file a single time". It seems to be intended that the implementation will use
this hint to perform drop-behind of that part of the file when the application
gets around to reading or writing it.However for reasons which aren't obvious (or sane?) I mapped
POSIX_FADV_NOREUSE onto POSIX_FADV_WILLNEED. ie: it does readahead.That's daft. So for now, make POSIX_FADV_NOREUSE a no-op.
This is a non-back-compatible change. If someone was using POSIX_FADV_NOREUSE
to perform readahead, they lose. The likelihood is low.If/when we later implement POSIX_FADV_NOREUSE things will get interesting - to
do it fully we'll need to maintain file offset/length ranges and peform all
sorts of complex tricks, and managing the lifetime of those ranges' data
structures will be interesting..A sensible implementation would probably ignore the file range and would
simply mark the entire file as needing some form of drop-behind treatment.Cc: Michael Kerrisk
