1704 6719 d 12 h cejka /kernel/trunk/ Fixed first letter size of subgroup name in Others.  
1702 6720 d 6 h cejka /kernel/trunk/ Kernel doxygen comments updated.  
1483 6732 d 6 h jermar /kernel/trunk/generic/src/ Implement recursive function for deallocating the whole B+tree.
Make use of this function in address space management.		  
1248 6767 d 3 h jermar /kernel/trunk/ Add some @file doxygen comments and improve already existing comments.  
1221 6771 d 21 h decky /kernel/trunk/ printf-related and other code cleanup  
1196 6778 d 7 h cejka /kernel/trunk/ Printf ported back from uspace to kernel.
Printf calls changed to match new conventions.		  
1177 6782 d 8 h jermar /kernel/trunk/generic/ Modify B+tree node key width to be 64-bit wide on all platforms.  
1164 6785 d 4 h jermar /kernel/trunk/generic/ Switch B+tree node allocation from malloc() to a dedicated slab - btree_node_slab.  
1150 6790 d 11 h jermar /kernel/trunk/generic/ Rename btree_node_left_sibling() to btree_leaf_node_left_neighbour()
and btree_node_right_sibling() to btree_leaf_node_right_neighbour()
as the left and right neighbours of a node needn't be its siblings.		  
1148 6790 d 22 h jermar /kernel/trunk/generic/src/ s/B+-tree/B+tree/  
1147 6790 d 22 h jermar /kernel/trunk/generic/ Deploy B+tree in address space area management.
Change as_remap() to check for conflicts with other address space areas only when the area in question grows.		  
1144 6793 d 2 h jermar /kernel/trunk/ Completed B+-tree support.
Enable btree_remove().
Reorder some static functions and group them together.
Fix order of nodes in the leaf_head list.		  
1142 6793 d 9 h jermar /kernel/trunk/ Update B+-tree code.
The code is there, btree_remove() has not been tested yet.
(Fixes, if any, are to come later today.)		  
1140 6795 d 2 h jermar /kernel/trunk/generic/ Change B+-tree from 2-3-4 tree to 2-3-4-5 tree by adding space for the fourth key.
This should make key removal easier.		  
1136 6799 d 1 h jermar /kernel/trunk/generic/src/adt/ Try to avoid splitting full B+-tree nodes by trying left or right rotation first.
(This improved memory consumption of this algorithm by some 40% - meassured on 101-item set).		  
1134 6800 d 4 h jermar /kernel/trunk/generic/src/adt/ Change B+-tree to:
- store lesser keys in a key's left subtree
- propagate the bigger of medians (if there are two medians) when splitting a node		  
1121 6801 d 23 h jermar /kernel/trunk/ Small textual changes.  
1101 6805 d 0 h jermar /kernel/trunk/ B+-tree implementation.
Currently supports only inserting and searching.
