same mechanism as NewOS, ie. using the iframe "stack" pointer (using the
new i386_get_current_iframe() function).
Implemented fork() support functions arch_{store|restore}_fork_frame().

team's address space - for internal use, anyway.
Added a ToDo: item to exec_team() to remind me of alarms and signals.
Started implementing fork_team() based on team_create_team() - it's not
completed (or even works), though.

Implemented _get_next_area_info() and _user_get_next_area_info().

reference to the address space, so that the calling team deletion function
doesn't have to do this.
delete_address_space() doesn't have to delete any areas anymore, since
at the point it's called, there is no area anymore, anyway: each area
holds a reference to the address space.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@9276 a95241bf-73f2-0310-859d-f6bbb57e9c96
This actually reflects the only usage of this function anyway, and thus,
fixes the resize_area() function.

vm_page no longer keeps a pointer to the vm_cache_ref but to the vm_cache.
This cleans the page handling when having to make an area copy-on-write;
regions belong to vm_cache_ref, pages to vm_cache.
Fixed some return types.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@9264 a95241bf-73f2-0310-859d-f6bbb57e9c96
It currently checks for temporary caches, but it should really only be used
with regions for anonymous memory.
Fixed some return types.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@9259 a95241bf-73f2-0310-859d-f6bbb57e9c96
Changed the way a vm_address_space is deleted: instead of having to explicitly
call vm_delete_aspace(), the last vm_put_aspace() will remove it.

Should be tested and verified more intensively, though.
Moved the creation, initialization, and deletion of the team_arg structure out of
team_create_team(); it's now also used by exec_team().
Renamed kfree_strings_array() to free_strings_array().
Renamed the fields of the team_arg structure to be more in sync with the names used
at other places.
Fixed the routine that copied the environment/arguments into the userland space.
Improved and fixed the user_copy_strings_array() function.

The FATAL() macro now uses dprintf() instead of printf() when TRACE_RLD is defined.

* Refactored common volume root to mount point resolution code into a
separate function.

As we currently don't have these environment variables set at init time, their values
are hardcoded for the moment.

The write functions didn't change the buffer address on a partial write

This fixes the build as unistd.h defined sleep() as well.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@9108 a95241bf-73f2-0310-859d-f6bbb57e9c96
It now prints a warning if the device driver doesn't handle iovecs correctly.
Again, this could lead to very strange behaviour.

devfs_read_stat() now (presumably temporary) sets the size of the device

if the size unequals zero.

* Turned sMountOpMutex into a recursive lock.
* Re-inserted sMountOpLock locking in vnode_path_to_vnode(). It doesn't
deadlock on mounting anymore. :-P
* Added a check in fs_mount(), whether the mount point is a directory. If
it wasn't, in general it wouldn't be possible to get its parent
directory.

extensions/ directory - which will contain glibc specific additions
to the POSIX standard (getopt() is here because of getopt_long() etc.).
Also added obstack functions.
Added wcsmbs to the build.

Implemented rootfs_write_stat() completely. rootfs_read_stat() now fills

rootfs_write_stat() now properly locks the node access.
Minor cleanup.

Removed the STREAM_TYPE_ constants.

Added note to dirfd() that it should be excluded from the kernel build
once the build system allows this.

console driver now clears the screen when it's initialized.
This improves the first impression of the standard boot process when
booting in text mode (which currently happens when you press "escape"
in the early boot stage).

IDE drivers :-)) don't respect the total amount of bytes to be read in the
former readv() (now read_pages()) call. This can potentially fix all sorts

Fixed the debug build.

recreates a race condition, having it here breaks the kernel as fs_mount()
calls this function and already holds the mutex.

sometimes even before anything meaty has been done at all
(e.g. in main()->init_statements()->shell_var_set_text()->
shell_value_init_text()->malloc()), I believe that's a problem not caused
by me. And I wasn't able to track it down.
