[PATCH 2/3] KVM: MMU: don't write-protect if have new mapping to unsync page
Two cases maybe happen in kvm_mmu_get_page() function: - one case is, the goal sp is already in cache, if the sp is unsync, we only need update it to assure this mapping is valid, but not mark it sync and not write-protect sp->gfn since it not broke unsync rule(one shadow page for a gfn) - another case i... 15 May 2010 07:13

[PATCH 3/4] drivers/hid: Eliminate use after free
From: Julia Lawall <julia(a)diku.dk> The skip label frees resp, which has not been allocated at the point of this goto and then does a break, based on the fact that err is non-zero. This is replaced by a break directly. A simplified version of the semantic match that finds this problem is as follows: (http://coc... 15 May 2010 06:08
