Re: I/O permission bitmap patch for oskit-mach

[Roland McGrath]

The io_bitmap_* functions can be static (and get inlined), no?  You left
machine_task_zone.  Btw, you could use a zone for the iopb's instead of
kalloc, since they are all the same size.  It's not much difference, but
maybe a wee bit faster.  With the alias decl, you should not need the
#define for base_tss any more.  It's clearer to just use ktss in the function.
