--- Comment #20 from H.J. Lu <hjl.tools at gmail dot com> ---
In Linux kernel 6.7.0 on x86-64, do_exit is changed from
do_exit:
endbr64
call <do_exit+0x9>
push %r15
push %r14
push %r13
push %r12
mov %rdi,%r12
push %rbp
push %rbx
mov %gs:0x0,%rbx
sub $0x28,%rsp
mov %gs:0x28,%rax
mov %rax,0x20(%rsp)
xor %eax,%eax
call *0x0(%rip) # <do_exit+0x39>
test $0x2,%ah
je <do_exit+0x8d3>
to
do_exit:
endbr64
call <do_exit+0x9>
sub $0x28,%rsp
mov %rdi,%r12
mov %gs:0x28,%rax
mov %rax,0x20(%rsp)
xor %eax,%eax
mov %gs:0x0,%rbx
call *0x0(%rip) # <do_exit+0x2f>
test $0x2,%ah
je <do_exit+0x8c9>
Kernel seems to work fine.
