| 2006-08-13 | namei returns locked parent dir inode for create / unlink | rtm | 1 | -3/+3 | |
| 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 | |||||

| fix acquire() to cli() *before* incrementing nlock make T_SYSCALL a trap gate, not an interrupt gate sadly, various crashes if you hold down a keyboard key... | |||||

| 2006-07-16 | Attempt to clean up newproc somewhat. | rsc | 1 | -8/+5 | |
| Also remove all calls to memcpy in favor of memmove, which has defined semantics when the ranges overlap. The fact that memcpy was working in console.c to scroll the screen is not guaranteed by all implementations. | |||||
| 2006-07-16 | New scheduler. | rsc | 1 | -1/+2 | |
| Removed cli and sti stack in favor of tracking number of locks held on each CPU and explicit conditionals in spinlock.c. | |||||

| 2006-07-15 | no more recursive locks | rtm | 1 | -9/+24 | |
| wakeup1() assumes you hold proc_table_lock sleep(chan, lock) provides atomic sleep-and-release to wait for condition ugly code in swtch/scheduler to implement new sleep fix lots of bugs in pipes, wait, and exit fix bugs if timer interrupt goes off in schedule() console locks per line, not per byte | |||||
