vec se ma asi takto - nevim o zadnem "hezkem" zpusobu jak to zjistit ale
imho by to melo jit takhle

struct proc {
   ....
           struct vmspace  *p_vmspace;     /* (b) Address space. */
   ....
}

struct vmspace {
   ....
           segsz_t vm_ssize;       /* stack size (pages) *
   ....
}

kde na stacku je ulozen (mimojine) ten environment, ale nemam to
overene. pak by se to dalo natahnout pres copyin()
ale uprimne receno - zjistovat environment z kernelu je dost prasarna -
k cemu to potrebujete? imho je cele reseni blbe, kdyz tam musite delat
takoveto veci..
