2531 6131 d 17 h jermar /trunk/uspace/ VFS work.
Implement VFS_REGISTER part of the protocol in the FAT file system.

IPC work.
Rename ipc_data_send_accept() to ipc_data_receive() and ipc_data_send_answer()
to ipc_data_deliver(). Introduce ipc_data_send().		  
2530 6132 d 8 h jermar /trunk/uspace/lib/libc/generic/ Pseudo thread -> fibril change in several comments.  
2522 6135 d 6 h jermar /trunk/uspace/lib/libc/ Add wrappers facilitating easy use of IPC_M_DATA_SEND calls and answers.  
2495 6199 d 21 h jermar /trunk/uspace/lib/libc/generic/io/ Formatting changes.  
2492 6205 d 20 h jermar /trunk/uspace/lib/libc/generic/ Add comment clarifying how a fibril waiting for a message gets rescheduled.  
2490 6207 d 20 h jermar /trunk/uspace/lib/libc/generic/ Improve comments in async.c  
2488 6209 d 15 h jermar /trunk/uspace/lib/libc/generic/ Improve comments in async.c  
2486 6209 d 19 h jermar /trunk/uspace/lib/libc/ Remove duplicit and empty time.h from libc.
Move timeval functions from async.c to time.c.		  
2485 6213 d 17 h jermar /trunk/uspace/lib/libc/generic/ More fibril/psthread cleanup.  
2484 6213 d 18 h jermar /trunk/uspace/lib/libc/generic/ More psthread/fibril cleanup.  
2483 6213 d 22 h jermar /trunk/uspace/lib/libc/ Remove fibril_join().
We cannot guarantee our assumptions that easily.
This broken feature is removed instead of fixing because there are now users of it.		  
2482 6214 d 13 h jermar /trunk/ Goodbye pseudo threads, welcome fibrils.
The renaming might still be incomplete.		  
2481 6214 d 14 h jermar /trunk/uspace/lib/libc/ 1. Implement simple joining of pseudo threads. Only one pseudo thread is allowed to join another pseudo
thread. The restriction is that both pseudo threads must be from the same thread (this is to simplify
synchronization). The joiner doesn't free anything from the joinee. It only gets its return value. Not
tested thoroughly yet.

2. Cleanup of a dead pseudo thread is done by the next scheduled pseudo thread. Not tested thoroughly yet.		  
2479 6219 d 0 h jermar /trunk/ New, better-structured, directory layout for uspace.  
2471 6224 d 18 h jermar /trunk/ Greatly improve comments in the IPC layer.
Now I think I finally start to understand our IPC internals :-)		  
2470 6228 d 16 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().		  
2469 6228 d 17 h jermar /trunk/uspace/libc/generic/ Fix a bug in userspace thread_create() that confused success of the
syscall with failure.		  
2445 6240 d 23 h decky /trunk/ initial merge of branches/fs
(not finished, huge cleanup is needed)		  
2436 6242 d 18 h jermar /trunk/ Fix two memory leaks.

In kernel, kernel_uarg structure needs to be deallocated when a thread
with userspace context is destroyed.

In userspace, the return value of the SYS_THREAD_CREATE must be checked
for error conditions and in case of error, uarg and stack must be freed
up.		  
2359 6255 d 3 h jermar /trunk/ Improve comments for the IPC subsystem.
Fix formatting and indentation.
