Description

The 2nd parameter of kill here should be 10, not 1<<10. Otherwise you'll get 1<<(1<<10) in os/src/syscall/process.rs#sys_kill

Research direction

Start with user/src/bin/sig_simple2.rs at the referenced kill call, then read os/src/syscall/process.rs at sys_kill to understand how the second parameter is handled. Done means the call passes the intended signal value and the resulting expression no longer applies an unintended nested shift.
