4348 5716 d 20 h svoboda /branches/dynload/ Merge latest trunk changes to dynload.  
4342 5718 d 8 h svoboda /branches/dynload/ Merge trunk changes up to r3889 to dynload.  
4337 5718 d 10 h svoboda /branches/dynload/ Merge changes in trunk up to r3741 to dynload.

3569 5890 d 18 h svoboda /branches/dynload/ Merge latest trunk changes into dynload.  
3448 5941 d 20 h svoboda /branches/dynload/ Merge latest trunk changes into dynload  
3190 6021 d 16 h svoboda /branches/dynload/ Remove vestiges of loading code coming from trunk  
3153 6035 d 15 h svoboda /branches/dynload/ Merge latest trunk changes into dynload

3149 6035 d 16 h svoboda /branches/dynload/ Merge trunk changes up to r3071 into dynload (broken)  
2927 6067 d 19 h decky /branches/dynload/ added dynload branch  
2907 6070 d 14 h jermar /trunk/kernel/generic/src/proc/ Improve comment for thread_create().  
2790 6113 d 19 h jermar /trunk/kernel/generic/src/proc/ Fix typo ALV tree vs. AVL tree.  
2712 6171 d 15 h decky /trunk/kernel/ prettyprint output  
2504 6358 d 10 h jermar /trunk/kernel/generic/ Give the AVL tree walkers the possibility to take an argument.
Each walker is now supposed to return a bool value to support walk termination.

Switch over from the tasks_btree B+tree to tasks_tree AVL tree.
This makes the fix for ticket #48 complete.		  
2502 6358 d 15 h jermar /trunk/kernel/generic/ Replace the threads_btree B+tree with an AVL tree. The new variable is called
threads_tree. For printing list of threads, use the new AVL tree walker
mechanism.

This solves half of ticket #48.		  
2487 6385 d 11 h jermar /trunk/kernel/generic/src/proc/ Kernel stack address was printed twice.  
2470 6404 d 8 h jermar /trunk/ Fix a double-free recently introduced in revision r2436.
Add a comment clarifying the life-cycle of the kernel_uarg structure.

Comment out the freeing of userspace thread stack while still running on it.
This should be fixed by implementing userspace version of thread_join().		  
2451 6413 d 9 h jermar /trunk/kernel/generic/ JoinMe -> Lingering  
2446 6416 d 13 h jermar /trunk/kernel/generic/ More efficient and simpler task termination.

Based on the assumption, that after its creation, only the task itself can create more threads for itself,
the last thread with userspace context to execute thread_exit() will perform futex and IPC cleanup. When
the task has no threads, it is destroyed. Both the cleanup and destruction is controlled by reference
counting.

As for userspace threads, even though there could be a global garbage collector for joining threads, it is
much simpler if the uinit thread detaches itself before switching to userspace.

task_kill() is now an idempotent operation. It just instructs the threads within a task to exit.

Change in the name of a thread state: Undead -> JoinMe.
