I search the commit mesage in the following url,but not find c6800e279a2 
commit

https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/log/?h=v5.19

@Cyril
I guess git describe ac6800e2 will serach the commit id because it is 
merge request"Merge tag 'fs.setgid.v6.0' of 
git://git.kernel.org/pub/scm/linux/kerne/git/brauner/linux"
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?h=426b4ca2d6a5

then it will serach brauner linux fs.setgid. branch
see the following url
https://git.kernel.org/pub/scm/linux/kernel/git/brauner/linux.git/log/?h=fs.setgid

so git describe ac6800e27 it says that it's a second commit on the top 
of 5.19-rc7.
