  "message": "pidns: make pid-\u003elevel and pid_ns-\u003elevel unsigned\n\nThese values represent the nesting level of a namespace and pids living in it,\nand it\u0027s always non-negative.\n\nTurning this from int to unsigned int saves some space in pid.c (11 bytes on\nx86 and 64 on ia64) by letting the compiler optimize the pid_nr_ns a bit.\nE.g.  on ia64 this removes the sign extension calls, which compiler adds to\noptimize access to pid-\u003enubers[ns-\u003elevel].\n\nSigned-off-by: Pavel Emelyanov \u003cxemul@openvz.org\u003e\nCc: \"Eric W.
