[RFC PATCH v7 35/78] KVM: x86: disable gpa_available optimization for fetch and page-walk NPF/EPT violations
From: Mircea C?rjaliu <mcirjaliu at bitdefender.com> This change is needed because the introspection tool can write-protect guest page tables, exec-protect heap/stack pages and let KVM emulate the instruction that caused these violations.

error in optim, within polr(): "initial value in 'vmmin' is not finite"
Hi all. I'm just starting to explore ordinal multinomial regression. My dataset is 300,000 rows, with an outcome (ordinal factor from 1 to 9) and five independent variables (all continuous). My first stab at it was this: pomod <- polr(Npf ~ o_stddev + o_skewness + o_kurtosis + o_acl_1e + dispersal, rlc, Hess=TRUE) And that worked; I got a good model fit. However, a variety of other things that I've tried give me this error: Error in optim(s0, fmin, gmin, method = "BFGS", ...) : initial value in 'vmmin'...

Adding new nodes to OCFS2?
I looked around, found older post which seems not applicable anymore. I have a cluster of 2 nodes right now, which has 3 OCFS2 file systems. All the file systems were formatted with 4 node slots. I added the two news nodes (by hand, by ocfs2console and o2cb_ctl), so my /etc/ofcfs/cluster.conf looks right: node: ip_port = 7777 ip_address = 192.168.201.1 number = 0

Samba write performance in kernel
hi, I would like to know is it possible to make writing file to samba completely in kernel? I'm using a slow CPU (FA526) , and the memory copy is even slower. The reading performance is over 7 MB/s, with mmap and sendfile enabled, while writing is only 4-5 MB/s. Without mmap and sendfile, reading from samba is also about 4-5 MB/s. I use Oprofile to profile writing file to samba and found
