Followup-For: Bug #1121155
I've sent a few fixes for regressions in supporting older kernels
directly to the corresponding upstream bugs.
Two more changes that are maybe not perfectly suited for upstream:
1)
Please add
BUILD_EXCLUSIVE_KERNEL_MIN="4.18"
to the generated dkms.conf
struct_size() was added by 610b15c50e86eb1e4b77274fabcaea29ac72d6a8 in
v4.18 and is used unconditionally in xrt-xocl-dkms
(That minimum setting is not perfect, since struct_size() was
backported to a few stable kernel branches but for Debian and
derivatives it should be sufficient).
2)

signal.h is not included transitively by all (old) kernel versions,
e.g. 5.5.0. There is a RHEL specific conditional further down to include
signal.h, I'm not sure how they would interact, maybe the two could be
merged.
