Hi!
The kernel build fails at fresh CURRENT. At first I get a couple of
same warnings like:
-----
clang -c -O -pipe -std=c99 -g -Wall -Wredundant-decls -Wnested-externs
-Wstrict-prototypes -Wmissing-prototypes -Wpointer-arith -Winline
-Wcast-qual -Wundef -Wno-pointer-sign -
fformat-extensions -Wmissing-include-dirs -fdiagnostics-show-option
-Wno-error-tautological-compare -Wno-error-empty-body
-Wno-error-parentheses-equality -nostdinc -I. -I/usr/
src/sys -I/usr/src/sys/contrib/altq -D_KERNEL
-DHAVE_KERNEL_OPTION_HEADERS -include opt_global.h -mno-aes -mno-avx
-mno-mmx -mno-sse -msoft-float -ffreestanding -fstack-protector
/usr/src/sys/cam/scsi/scsi_cd.c
/usr/src/sys/cam/scsi/scsi_cd.c:571:7: warning: implicit declaration of
function 'scsi_extract_sense_ccb' is invalid in C99
[-Wimplicit-function-declaration]
scsi_extract_sense_ccb(ccb,

And then I get an error:
-----
