I want to review and test the series, but I cannot seem to find the base
commit in the master branch:
$ git show --oneline
87320be9f0d2 (HEAD -> master, origin/master, origin/HEAD) Merge tag 'net-7.2-rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net
$ git show 98f826f3c500fda08d51fca434b7aefa6a2
fatal: ambiguous argument '98f826f3c500fda08d51fca434b7aefa6a2': unknown revision or path not in the working tree.
Thanks,
Alex
