Applied your 3 patches

into kernel.org Linux Kernel 4.1.7, but Non-systemd Debian still boots
into an emergency shell
[...]
mount: mounting /dev/sdaX on /root failed: no such file or directory
Target fileystem doesn't have requested /sbin/init
mount: mounting /dev on /root/dev failed: no such file or directory
No init found. Try passing init= bootarg.
[...]
Typing dmesg:
[...]
reiser4[exe(801)]: reiser4_init_csum_tfm
(fs/reiser4/checksum.c:11)[intelfx-81]:WARNING: Could not load crc32c
driver
In a couple of days I will build the kernel "the Debian way"; I will
specify -- in relevant module section, at file [kernel source
tree]debian/installer/package-list:
[...]
Package: reiser4-modules
Depends: kernel-image crc-modules # <--- will add that
Priority: extra
Description: Reiser4 filesystem support
This package contains the Reiser4 filesystem module for the kernel.
[...]
As well as at /usr/share/kernel-wedge/package-list
We will see what happens.
