Ok. I was wondering wether it meant something that the same pc number
appeared twice in the lock line. Or is it just one number that gets
printed twice?
Acid tells me:
term% acid 9pcdisk
9pcdisk:386 plan 9 boot image
/sys/lib/acid/port
/sys/lib/acid/386
acid: src(0x80104e08)
/sys/src/9/pc/mmu.c:332
327
328 mach0 = MACHP(0);
329
330 lock(&mmukmaplock);
331
>332 if((pte = mmuwalk(mach0->pdb, va, 1, 0)) == nil){
333 unlock(&mmukmaplock);
334 return 0;
335 }
336 if(!(*pte & PTESIZE) && mmuwalk(mach0->pdb, va, 2, 0) == nil){
337 unlock(&mmukmaplock);
acid:
My /sys/src/9/pc/mmu.c is of Apr 11 2002.
In case it helpful: I compiled that kernel on Feb 18 2003.
Axel.
