Re: [PATCH 6.1 00/92] 6.1.139-rc1 review

[Hardik Garg <hargar@linux.microsoft.com>]

The kernel, bpf tool and perf tool builds fine for v6.1.139-rc1 on x86
and arm64 Azure VM.

KernelCI with LTP and kselftest results: Tree: stable/linux-6.1.y 
<https://dashboard.kernelci.org/tree/02b72ccb5f9df707a763d9f7163d7918d3aff0b7?o=microsoft&p=t&ti%7Cc=v6.1.138&ti%7Cch=02b72ccb5f9df707a763d9f7163d7918d3aff0b7&ti%7Cgb=linux-6.1.y&ti%7Cgu=https%3A%2F%2Fgit.kernel.org%2Fpub%2Fscm%2Flinux%2Fkernel%2Fgit%2Fstable%2Flinux.git&ti%7Ct=stable>
