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.

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
OOPS
the 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.

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 Signed-off-by: Matthieu CASTET <castet.matthieu@free.fr> Signed-off-by: Uwe Bugla <uwe.bugla@gmx.de> Cc: Bjorn Helgaas <bjorn.helgaas@hp.com> Cc: Adam Belay <ambx1@neo.rr.com> Cc: "Brown, Len" <len.brown@intel.com> Acked-by: Shaohua Li <shaohua.li@intel.com> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
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 eof Signed-off-by: Chris Mason <mason@suse.com> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
