But they still need to be fixed.
With PREEMPT_RT enabled:
# trace-cmd start -e syscalls
# trace-cmd show
bash-1165 [001] DBZ.f 269.955644: sys_ioctl(fd: 0xff, cmd: 0x5413, arg: 0x7fffd3d6a2d0)
bash-1165 [001] DBZ.f 269.955649: sys_ioctl -> 0x0
bash-1165 [001] DBZ.f 269.955694: sys_rt_sigprocmask(how: 2, nset: 0x7fffd3d6a3a0, oset: 0, sigsetsize: 8)
bash-1165 [001] DBZ.f 269.955698: sys_rt_sigprocmask -> 0x0
bash-1165 [001] DBZ.f 269.955715: sys_wait4(upid: 0xffffffffffffffff, stat_addr: 0x7fffd3d69c50, options: 0xb, ru: 0)
bash-1165 [001] DBZ.f 269.955722: sys_wait4 -> 0xfffffffffffffff6
bash-1165 [001] DBZ.f 269.955725: sys_rt_sigreturn()
bash-1165 [001] DBZ.f 269.955758: sys_rt_sigaction(sig: 2, act: 0x7fffd3d6a2e0, oact: 0x7fffd3d6a380, sigsetsize: 8)
bash-1165 [001] DBZ.f 269.955762: sys_rt_sigaction -> 0x0
^^^^^
This is just garbage.
