• caafa4324   pidns: make pid->level and pid_ns->level unsigned ... Browse Code »

  These values represent the nesting level of a namespace and pids living in it,
  and it's always non-negative.

  Turning this from int to unsigned int saves some space in pid.c (11 bytes on
  x86 and 64 on ia64) by letting the compiler optimize the pid_nr_ns a bit.
  E.g. on ia64 this removes the sign extension calls, which compiler adds to
  optimize access to pid->nubers[ns->level].

• 74bd59bb3   namespaces: cleanup the code managed with PID_NS option ... Browse Code »

  Just like with the user namespaces, move the namespace management code into
  the separate .c file and mark the (already existing) PID_NS option as "depend
  on NAMESPACES"
