BUG_ON() already uses unlikely() inside its definition if possible,
It's true for asm-generic/bug.h.
But for archs which has defined HAVE_ARCH_BUG,
unlikely() is not always included in it.
IMHO, if this condition happens, it should be a bug of the arch
So that means we should fix that first :)
Could you please to identify a piece of kernel code which provides an
example as the condition you mentioned ?
So I can have a look firstly.
# line filename / context / line
1 35 arch/mips/include/asm/bug.h<<HAVE_ARCH_BUG_ON>>
2 115 arch/powerpc/include/asm/bug.h<<HAVE_ARCH_BUG_ON>>
