Greg Kroah-Hartman
maintainerI'm announcing the release of the 5.10.119 kernel.
All users of the 5.10 kernel series must upgrade.
The updated 5.10.y git tree can be found at:
git://git.kernel.org/pub/scm/linux/kernel/git/stable/linux-stable.git linux-5.10.y
and can be browsed at the normal kernel.org git web browser:
https://git.kernel.org/?p=linux/kernel/git/stable/linux-stable.git;a=summary
thanks,
greg k-h
