I'm announcing the release of the 5.0.21 kernel.
All users of the 5.0 kernel series must upgrade.
Note, this is the LAST 5.0.y kernel to be released. It is now end-of-life. Please move to the 5.1.y kernel tree at this point in time.
The updated 5.0.y git tree can be found at: git://git.kernel.org/pub/scm/linux/kernel/git/stable/linux-stable.git linux-5.0.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%3Ba=summa...
thanks,
greg k-h

I'm announcing the release of the 5.0.21 kernel.
All users of the 5.0 kernel series must upgrade.
Note, this is the LAST 5.0.y kernel to be released. It is now end-of-life. Please move to the 5.1.y kernel tree at this point in time.
The updated 5.0.y git tree can be found at: git://git.kernel.org/pub/scm/linux/kernel/git/stable/linux-stable.git linux-5.0.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%3Ba=summa...
