Passing "0x%p" to sprintf results in double "0x" being printed.
This causes a dtrace script compilation failure when "-d" flag is specified:
(...) /(self->ev32[(uintptr_t)arg0]) && (timestamp - self->ev32[(uintptr_t)arg0] >= 0x0x64)/ (...) lockstat: ^^^^ D program ^^^^ lockstat: failed to compile program: syntax error near "x64"
