This may be little bit off-topic... but stable kernel.org kernels
can also bit-rot badly because of "selective" backporting... as in
anything that does not apply cleanly gets dropped regardless of
how critical they are.
I will give you one example: Intel WiFi (iwlwifi) on 4.19.y
kernel.org stable kernels is currently missing many critical
locking fixes. As a result, that in-tree iwlwifi driver causes
erratic behavior to random unrelated processes, and has been doing
so for many months now. My not-so-politically correct opinion is
that in-tree iwlwifi is completely FUBAR unless someone steps up
to do professional quality backport of those locking fixes from
upstream out-of-tree Intel version [1] [2] of the driver. For me
only way to get properly working WiFi on my laptop computer is to
compile that Intel out-of-tree version. Sad, but true.
