university students again.  The documentation could be extended for more
sources which are equipped by structured comments for recent 2.6 kernels.  I
have tried to proceed with that task.  I have done that more times from 2.6.0
time and it gets boring to do same changes again and again.  Linux kernel
compiles after changes for i386 and ARM targets.  I have added references to
some more files into kernel-api book, I have added some section names as well.
 So please, check that changes do not break something and that categories are
not too much skewed.

I have changed kernel-doc to accept "fastcall" and "asmlinkage" words reserved
by kernel convention.  Most of the other changes are modifications in the
comments to make kernel-doc happy, accept some parameters description and do
not bail out on errors.  Changed <pid> to @pid in the description, moved some
#ifdef before comments to correct function to comments bindings, etc.

You can see result of the modified documentation build at
  http://cmp.felk.cvut.cz/~pisa/linux/lkdb-2.6.11.tar.gz

Some more sources are ready to be included into kernel-doc generated

section names added and probably some more chaos introduced as result of quick

ext3_get_block_handle(), which was inherited from ext2, becomes unecessary
for ext3, since we have already obtained the ei->truncate_sem in
ext3_get_block_handle() before calling ext3_alloc_branch().  The
ei->truncate_sem is already there to block concurrent truncate and block
allocation on the same inode.  So the inode's indirect addressing tree
won't be changed after we grab that semaphore.

We could, after get the semaphore, re-verify the branch is up-to-date or
not.  If it has been changed, then get the updated branch.  If we still
need block allocation, we will have a safe version of the branch to work
with in the ext3_find_goal()/ext3_splice_branch().

The code becomes more readable after remove those retry logic.  The patch

value of zero in visual_init(), even if we were using 512 character fonts

It's trivial for the resize option to auto-get the underlying device size,

Since of the different reiserfs option parser (which does not use the
superior match_token used by almost every other filesystem), I've had to
use the "resize=auto" and not "resize" option to specify this behaviour.
Changing the option parser to the kernel one wouldn't be bad but I've no
time to do this cleanup in this moment.

Btw, the mount(8) man page should be updated to include this option.  Cc

The memory setup didn't take care of memory holes and this makes the memory
management think there would be more memory available than there is in
reality.  That causes the OOM killer to kill processes even if there is enough
memory left that can be written to the swap space.

The patch fixes this by using free_area_init_node with an array of memory
holes instead of free_area_init.  Further the patch cleans up the code in
setup.c by splitting setup_arch into smaller pieces.
