Fault injection capabilities[Documentation/fault-injection/fault-injection.rst]
facilitate testing of the stability of the Linux kernel by providing
means to force a number of kernel interfaces to return error
codes. This patch series proposes adding such fault injection
capability into LSM hooks.

The intent is to make it possible to test whether the existing kernel
code properly handles negative return values of LSM hooks. Syzbot
[https://github.com/google/syzkaller/blob/master/docs/syzbot.md] will
automatically do that with the aid of instrumentation tools once these
changes are merged.
[...]

What tree should these changes go to?

Is there anyone else who is not on the recipient list but still might
be interested in the series?
