CURRENT: exec_machdep.c:80:2: error: KDB must be enabled in order for DDB

[FreeBSD User]

Hello,

for customising my world and kernel, I try to "overlay" GENERIC via included 
files containing
"nodevice" and "nooptions" tags starting from a top level config file like

include GENERIC
include NODEVICE-GENERIC
include SPECIAL

Within "NODEVICE-GENERIC" I utilize
[...]
# Debugging support.  Always need this:
nooptions   KDB # Enable kernel debugger support.
nooptions   KDB_TRACE   # Print a stack trace for a panic.
# For full debugger support use (turn off in stable branch):
include "std.nodebug"
[...]

to disable KDB. The include "std.debug" in GENERIC is new, prior to its 
occurence the sketched
scheme worked fine for me, but now I get this error while perfoming "make -jX 
buildworld
buildkernel":

[...]
/usr/src/sys/amd64/amd64/exec_machdep.c:80:2: error: KDB must be enabled in 
order for DDB to
work! 80 | #error KDB must be enabled in order for DDB to work!
  |  ^
[...]

Apart from the recommendation not to disable KDB in CURRENT, is there a way to 
disable
debugging features and mimik a stable branch?

Thanks in advance,

oh

This time at Netflix we had limited testing capacity.  The test was run
on 3 pairs of machines (normally we have > 20).  Anyway, no stability
issues neither performance regressions were found by our testing.

Since I didn't receive any negative feedback on the stabilization snapshot,
the stabilization week is declared completed.

I created a branch stabweek-2024-May that has two bugfixes cherry-picked:

4c053c17f2c8a715988f215d16284879857ca376 (affects 32-bit ZFS users)
2780e5f43d5b0e8b155472300ee63816a660780e (affects users of linuxulator)

The branch is published at https://github.com/glebius/FreeBSD.

For those, who want to recreate the branch without using my repo:

git checkout -b stabweek-2024-May cca0ce62f367d03ed429bf99e41e6aca8cb7f2ac
git cherry-pick -x 4c053c17f2c8a715988f215d16284879857ca376
git cherry-pick -x 2780e5f43d5b0e8b155472300ee63816a660780e
