SubjectRe: [PATCH 00/11] xz: Updates to license, filters, and compression options
From
Just in case it hasn't been brought to the kernel's attention, the xz 
project has been compromised in its upstream repo, and versions 5.6.0
and 5.6.1 attempt to load a backdoor into SSH. I suggest any patches
associated with Lasse Collin, Jia Tan, or tukaani.org  be held until
that matter is fully resolved. And all their previous work needs to be
re-examined with this in mind.
