it's necessary for efficency of code.
when someCodition is FALSE, it's no cost on BUG().
but when you changed to BUG_ON(), there is always a cost on BUG_ON() both

Hello,
Does the file syscall_table_32.S under 'arch/x86/kernel' define syscalls for
both 32 bit and 64 bit architectures under x86 because I cannot find a file
for making syscall table entrys for x86_64.
Curiously there is a file called syscall_64.c which seems to define pointers
and references t
Hallo Group Members
Can You ell me what is it for?

I think the answer is found in the Intel manual -
