# Fix-validation kernel build (guest, root):
#   sources: pristine with-src snapshot + ONLY the combined DF-5287+DF-5288
#            fix.diff content applied to sys/bus/u4b/usb_generic.c and
#            sys/bus/u4b/usb_dev.h (verified: 7 DF-528x marker comments)
#   command: cd /usr/src && make -j 6 nativekernel KERNCONF=X86_64_GENERIC
#   result:  BUILD_RC=0   (full -Werror kernel build, ~7.5 minutes)
#   install: cd /usr/src && make installkernel KERNCONF=X86_64_GENERIC -> INSTALL_RC=0
#   booted:  DragonFly 6.5-DEVELOPMENT #1: Fri Oct  2 05:05:50 UTC 2026
#
# NOTE: the full untrimmed compiler transcript lived in the guest's /tmp
# (memory filesystem) and was wiped by the validation reboot; the rc values
# above were captured from the ssh sessions.  A first iteration of the fix
# (before the lock-balance correction documented in fix_validation.md)
# also built cleanly -- i.e. these rc values reflect the corrected fix.
