SELinux: Add new labeling type native labels
On Wed, 7 Jul 2010, David P. Quigley wrote: There currently doesn't exist a labeling type that is adequate for use with labeled NFS. Since NFS doesn't really support xattrs we can't use the use xattr labeling behavior. For this we developed a new labeling type. The native labeling type is used solely by N... 9 Jul 2010 10:33
FYI: mmap_sem OOM patch
As I mentioned this in my MM discussion proposal, I am sending the following patch for discussion. This helps some workloads we use, that are normally run with little memory headroom and get occasionally pushed over the edge to OOM.

[RFC/RFT PATCH] cfq-iosched: Implement cfq group idling
Currently we idle on sequential queues and allow dispatch from a single queue and that can become a bottleneck on higher end storage. For example on my HP EVA, I can run multiple sequential streams and achieve top BW of around 350 MB/s. But with CFQ, dispatching from single queue does not keep the array busy (limit... 7 Jul 2010 20:06
