I prefer to just add them at the bottom of the list. (slowly recovering from my backlog) I noticed some new syscalls got added recently: | :1515:2: warning: #warning syscall rt_tgsigqueueinfo not imple= mented | :1519:2: warning: #warning syscall perf_counter_open not imple= mented Probably I should wire those up first (for 2.6.31, if still possible). Next I should reserve 333..336 for you?
