Subject: [PATCH] Replace generic_make_request with submit_bio_noacct.
<Author: jwiele@redhat.com>
In kernel 5.9, generic_make_request has been renamed to
submit_bio_noacct to more accurately describe its
function. There is a comment in vdo/kernel/kernelLayer.c
referencing generic_make_request which is not touched by this
change because the whole lengthy comment will have to be
massively revised or even removed for upstreaming.
The doxygen comments in dmvdo.c and dmDory.c that reference
generic_make_request cannot easily be made conditional because
doxygen does not process preprocessor directives within
comments. The comments can be rephrased to simply refer to bio
submission because the exact name of the function used to do
the submission is not critical to the meaning of the comments.

Subject: [PATCH] Eliminated obsolete function smp_read_barrier_depends.
<Author: jwiele@redhat.com>
In Kernels newer than 5.9 or so, smp_read_barrier_depends has
been removed because its functionality is provided by
READ_ONCE. See: https://lkml.org/lkml/2019/11/8/1021
We provide a user space implementation that is empty for the
four primary platforms we test on. That can be deleted. Some
additional barriers can be added if we find that some platform
requires them.
Pair: sweeettea
.../funnelQueue.c
Replaced the call to smp_read_barrier_depends with a comment
noting that an additional barrier may be needed in the
future for some platforms such as Alpha.

Pair: sclafani
.../memoryLinuxKernel.c
Updated to have __vmalloc() with two arguments for 5.8+ kernels.
For now, it is ifdef'd for 5.8+ kernels; we will remove the
ifdef at some point after the lab has been updated to have
no Fedora machines with an earlier kernel.

Subject: [PATCH] Update procfs args for kernel 5.6 and above.
With commit d56c0d45f0e27f814e87a1676b6bdccccbc252e9 in the kernel, proc calls need to use 'struct proc_ops' instead of 'struct file_operations'. This commit applies that requirement for kernels 5.6 and newer.

Subject: [PATCH] Update time types for newer kernels
<Author: jwiele@redhat.com>
Newer kernels have removed time types and functions that are
specific to user space APIs as part of the effort to use
ktime_t for all kernel timekeeping. Luckily, UDS only uses
timespec and timeval in user space. UDS uses time_t in stats,
but time_t is just a number of seconds, and in modern systems
should be a 64 bit integer, even on 32 bit systems, so it can
be compatibly replaced with int64_t. A static assertion will
check that assumption.
Pair: sweettea
.../timeUtils.h
Add a function to convert absolute nanosecond time to
milliseconds.
Wrap user space specific functions with "#ifndef __KERNEL__".
Correct the comments on the user space specific functions.
.../timeUtils.c
Add a static assertion that time_t is the same as int64_t.
.../indexLayout.c
Use the new absolute time to milliseconds function in lieu of
the old getTimeMS function which was needed when user space
time had a different representation from kernel space time,
but can now be replaced with a simpler function.
.../uds.h
.../indexSession.c
Represent time in stats as int64_t instead of time_t.
