Tate, Hongliang Tian 659f079c2d Revise the doc of OSTD's scheduling module 2025-07-29 21:58:23 +08:00
Wei Zhang 8a801676ab Disallow masking SIGKILL and SIGSTOP in user space 
According to the Linux man pages[1], "It is not possible to block SIGKILL
or SIGSTOP. Attempts to do so are silently ignored." This patch ensures
compliance by explicitly removing SIGKILL and SIGSTOP from the signal
mask in the `MaskOp::SetMask` operation of the `rt_sigprocmask` syscall.
