-Subject: [PATCH] apparmor: don't try to mmap empty files
-
-In case empty profile files linger somehow (eg. powerloss or
-oom killer etc. between creating and writing the file) we
-tried to use mmap() with a length of 0 which is invalid.
-Let's treat this as if it did not exist.

Note that we don't actually make use of this anymore, since
we switched to the generated profiles which already do this.
# FIXME: This currently doesn't work due to the apparmor parser treating those as allowing all mounts.
# mount options=(rw,make-slave) -> **,

In debian buster, some libnss plugins (if installed) can
cause getpwent to segfault instead of erroring out cleanly.
