Analyze and fix the following issue in the Linux kernel code: xfs: fix double xfs_perag_rele() in xfs_filestream_pick_ag()
Problem Details: xfs_bmap_longest_free_extent() can return an error when accessing the AGF fails. In this case, the behaviour of xfs_filestream_pick_ag() is conditional on the error. We may continue the loop, or break out of it. The error handling after the loop cleans up the perag reference held when the break occurs....

Problem Details: Move SVM's call to trace_kvm_exit() from the "slow" VM-Exit handler to svm_vcpu_run() so that KVM traces fastpath VM-Exits that re-enter the guest without bouncing through the slow path. This bug is benign in the current code base as KVM doesn't currently support any such exits on SVM. Fixes: a9ab13f...
