I can reproduce the problem. I rebased this commit onto v6.8.7, I can still
observe the problem.

No immediate idea what is the problem. Backtrace from gdb goes crazy:

(gdb) bt
#0  0xffffffffb2074ded in ?? ()
#1  0x00000000000000a1 in ?? ()
#2  0x00000000000000a1 in ?? ()
#3  0x000000007ffff000 in ?? ()
#4  0x00000000543ff000 in ?? ()
#5  0x0000000000000000 in ?? ()

@akpm: drop this commit until this is figured out?

Best regards,
Nam
