[RFC][PATCH 1/9] abstract kvm x86 mmu->n_free_mmu_pages
First of all, I think "free" is a poor name for this value. In this context, it means, "the number of mmu pages which this kvm instance should be able to allocate." To me, "free" implies much more that the objects are there and ready for use. I think "available" is a much better description, especially when yo... 15 Jun 2010 10:55

[PATCH 1/1] FS: btrfs, use helpers for rlimits
Make sure compiler won't do weird things with limits. E.g. fetching them twice may return 2 different values after writable limits are implemented. I.e. either use rlimit helpers added in 3e10e716abf3c71bdb5d86b8f507f9e72236c9cd or ACCESS_ONCE if not applicable. Signed-off-by: Jiri Slaby <jslaby(a)suse.cz> Cc:... 15 Jun 2010 10:55

[RFC][PATCH 2/9] rename x86 kvm->arch.n_alloc_mmu_pages
Again, I think this is a poor choice of names. This value truly means, "the number of pages which _may_ be allocated". But, reading the value, "n_alloc_mmu_pages", I'm unable to think of anything it should mean other than "the number of allocated mmu pages", which is dead wrong. It's really the high watermar... 15 Jun 2010 10:55

[RFC][PATCH 4/9] create aggregate kvm_total_used_mmu_pages value
Note: this is the real meat of the patch set. It can be applied up to this point, and everything will probably be improved, at least a bit. Of slab shrinkers, the VM code says: * Note that 'shrink' will be passed nr_to_scan == 0 when the VM is * querying the cache size, so a fastpath for that case is appr... 15 Jun 2010 10:55

[PATCH 1/1] X86: pci, fix section mismatch
pcibios_scan_specific_bus calls pci_scan_bus_on_node which is __devinit. Mark pcibios_scan_specific_bus __devinit as well since all users are now __init or __devinit.

XFS status update for May 2010
In May 2010 we saw the long awaited release of Linux 2.6.34, which includes a large XFS update. The most important features appearing in 2.6.34 was the new inode and quota flushing code, which leads to much better I/O patterns for metadata-intensive workloads. Additionally support for synchronous NFS exports has ... 15 Jun 2010 09:48
