FWIW, I'd do that in handle_signal() when hitting a syscall restart. BTW, is everything in your pt_regs safe to modify? I.e. could bogus values put there by sigreturn lead to something like kernel mode being retained when you return from syscall or interesting flags being set, etc.? -- To unsubscribe from this list: send the line "unsubscribe linux-arch" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
