The previous patch somewhat diverted the train of thought. Here I am trying to bring the valued reader back on track. Signed-off-by:

I was grepping through the code and some `grep ganularity -R .` didn't catch what I thought. Then looking closer I saw the term "granuality" used in only four places (in comments) and granularity in many more places describing the same idea. Some other facts: dictionary.com does not know such a word define:granuality on google is not found (and pages for granuality are mostly related to patches to the kernel) it has not been discussed as a term on LKML, AFAICS (=Can Search) To be consistent, I think granularity should be used everywhere.

Commit 70674f95: [PATCH] Optimize select/poll by putting small data sets on the stack resulted in the poll stack being 4-byte aligned on 64-bit architectures, causing misaligned accesses to elements in the array. This patch fixes it by declaring the stack in terms of 'long' instead of 'char'. Force alignment of poll and select stacks to long to avoid unaligned access on 64 bit architectures. Signed-off-by:

The attached patch documents the Linux kernel's memory barriers. I've updated it from the comments I've been given. The per-arch notes sections are gone because it's clear that there are so many exceptions, that it's not worth having them. I've added a list of references to other documents. I've tried to get rid of the concept of memory accesses appearing on the bus; what matters is apparent behaviour with respect to other observers in the system. Interrupts barrier effects are now considered to be non-existent. They may be there, but you may not rely on them. I've added a couple of definition sections at the top of the document: one to specify the minimum execution model that may be assumed, the other to specify what this document refers to by the term "memory". I've made greater mention of the use of mmiowb(). I've adjusted the way in which caches are described, and described the fun that can be had with cache coherence maintenance being unordered and data dependency not being necessarily implicit. I've described (smp_)read_barrier_depends(). I've rearranged the order of the sections, so that memory barriers are discussed in abstract first, and then described the memory barrier facilities available on Linux, before going on to more real-world discussions and examples. I've added information about the lack of memory barriering effects with atomic ops and bitops. I've added information about control dependencies. I've added more diagrams to illustrate caching interactions between CPUs. Signed-off-by:

Wrong error path in dup_fd() - it should return NULL on error, not an address of already freed memory :/ Triggered by OpenVZ stress test suite. What is interesting is that it was causing different oopses in RCU like below: Call Trace: [<c013492c>] rcu_do_batch+0x2c/0x80 [<c0134bdd>] rcu_process_callbacks+0x3d/0x70 [<c0126cf3>] tasklet_action+0x73/0xe0 [<c01269aa>] __do_softirq+0x10a/0x130 [<c01058ff>] do_softirq+0x4f/0x60 ======================= [<c0113817>] smp_apic_timer_interrupt+0x77/0x110 [<c0103b54>] apic_timer_interrupt+0x1c/0x24 Code: Bad EIP value. <0>Kernel panic - not syncing: Fatal exception in interrupt Signed-Off-By:

Currently a device failure during recovery leaves bits set in the bitmap. This normally isn't a problem as the offending device will be rejected because of errors. However if device re-adding is being used with non-persistent bitmaps, this can be a problem. Signed-off-by:
