| 2006-08-15 | no more proc[] entry per cpu for idle loop | rtm | 8 | -616/+456 | |
| each cpu[] has its own gdt and tss no per-proc gdt or tss, re-write cpu's in scheduler (you win, cliff) main0() switches to cpu[0].mpstack | |||||

| don't hold fd table lock across idecref() (latter does block i/o) idecref calls iput() in case last ref -> freeing inode dir size is 512 * # blocks, so readi/writei &c work unlink deletes dirent even if ip->nlink > 0 | |||||
| 2006-08-13 | zero freed blocks | kaashoek | 2 | -8/+34 | |
| multi-block directories track size of directory (size = number entries in use) should namei (and other code that scans through directories) scan through all blocks of a directory and not use size? | |||||

| 2006-08-10 | interrupts could be recursive since lapic_eoi() called before rti | rtm | 16 | -28/+194 | |
