Hi Willy,

I am sorry for the delay on this. I was traveling last week
and getting back to digging myself out of emails.

I am having trouble pulling this request though:

git request-pull https://git.kernel.org/pub/scm/linux/kernel/git/wtarreau/nolibc.git/ 20230806-for-6.6-1

gives me the following error

fatal: Not a valid revision: git.kernel.org/pub/scm/linux/kernel/git/wtarreau/nolibc.git/

I don't see a tag at https://git.kernel.org/pub/scm/linux/kernel/git/wtarreau/nolibc.git

thanks,
