FTR, this is the silly

In function 'memcpy_and_pad.constprop',
    inlined from 'nvmet_execute_identify_ctrl' at
/kisskb/src/drivers/nvme/target/admin-cmd.c:346:2,
    inlined from 'nvmet_execute_identify' at
/kisskb/src/drivers/nvme/target/admin-cmd.c:617:10:
/kisskb/src/arch/m68k/include/asm/string.h:72:25: warning:
'__builtin_memcpy' forming offset 8 is out of the bounds [0, 7]
[-Warray-bounds]

which happens every point release, when strlen(UTS_RELEASE) is
smaller than 8.

when I'm talking to journalists I just say "programmer" or something like that.
