To pick the changes in: 1b870fa5573e260b ("kvm: stats: tell userspace which values are boolean") That just rebuilds perf, as these patches don't add any new KVM ioctl to be harvested for the the 'perf trace' ioctl syscall argument beautifiers.

bpf: Add flags arg to bpf_dynptr_read and bpf_dynptr_write APIs

2022-07-08T08:55:53Z

Commit 13bbbfbea759 ("bpf: Add bpf_dynptr_read and bpf_dynptr_write") added the bpf_dynptr_write() and bpf_dynptr_read() APIs. However, it will be needed for some dynptr types to pass in flags as well (e.g. when writing to a skb, the user may like to invalidate the hash or recompute the checksum). This patch adds a "u64 flags" arg to the bpf_dynptr_read() and bpf_dynptr_write() APIs before their UAPI signature freezes where we then cannot change them anymore with a 5.19.x released kernel.
