[PATCH] radix_tree_tag_get() is not as safe as the docs make out [ver #2]
radix_tree_tag_get() is not safe to use concurrently with radix_tree_tag_set() or radix_tree_tag_clear(). The problem is that the double tag_get() in radix_tree_tag_get(): if (!tag_get(node, tag, offset)) saw_unset_tag = 1; if (height == 1) { int ret = tag_get(node, tag, offset); may see the value... 6 Apr 2010 18:43

[PATCH #slabh] nodemask: include slab.h from drivers/base/node.c
NODEMASK_ALLOC/FREE are mapped to kmalloc/free if NODES_SHIFT > 8. Among its several users, drivers/base/node.c wasn't including slab.h leading to build failure if NODES_SHIFT > 8. Include slab.h from drivers/base/node.c. This isn't an ideal solution but including slab.h directly from nodemask.h is not an optio... 6 Apr 2010 18:43

radix_tree_tag_get() is not as safe as the docs make out
Nick Piggin <npiggin(a)suse.de> wrote: Nack, just drop the BUG_ON. I can do that. I don't know what you mean by "untrustworthy answer". I was thinking that the answer you get from radix_tree_tag_get() may be invalid if the tag chain is being modified as you read it. So if you do: rcu_read_lock() .... 6 Apr 2010 17:34

[PATCH] x86/PCI: ignore Consumer/Producer bit in ACPI window descriptions
ACPI Address Space Descriptors (used in _CRS) have a Consumer/Producer bit that is supposed to distinguish regions that are consumed directly by a device from those that are forwarded ("produced") by a bridge. But BIOSes have apparently not used this consistently, and Windows seems to ignore it, so I think Linux ... 6 Apr 2010 16:27
