rbtree: Undo augmented trees performance damage and regression

2010-07-05T12:43:50Z

Reimplement augmented RB-trees without sprinkling extra branches all over the RB-tree code (which lives in the scheduler hot path). This approach is 'borrowed' from Fabio's BFQ implementation and relies on traversing the rebalance path after the RB-tree-op to correct the heap property for insertion/removal and make up for the damage done by the tree rotations. For insertion the rebalance path is trivially that from the new node upwards to the root, for removal it is that from the deepest node in the path from the to be removed node that will still be around after the removal. [ This patch also fixes a video driver regression reported by Ali Gholami Rudi - the memtype->subtree_max_end was updated incorrectly. ] Acked-by: Suresh Siddha Acked-by: Venkatesh Pallipadi Signed-off-by: Peter Zijlstra Tested-by: Ali Gholami Rudi Cc: Fabio Checconi Cc: "H.

module: initialize module dynamic debug later

2010-07-05T03:17:22Z

We should initialize the module dynamic debug datastructures only after determining that the module is not loaded yet. This fixes a bug that introduced in 2.6.35-rc2, where when a trying to load a module twice, we also load it's dynamic printing data twice which causes all sorts of nasty issues. Also handle the dynamic debug cleanup later on failure. Signed-off-by: Yehuda Sadeh Signed-off-by: Rusty Russell (removed a #ifdef) Signed-off-by: Linus Torvalds

genalloc: fix allocation from end of pool

2010-06-29T22:29:30Z

bitmap_find_next_zero_area requires the size of the bitmap, we instead passed the last suitable position. This made it impossible to allocate from the end of the pool. Fixes a regression introduced by 243797f59b748f679ab88d456fcc4f92236d724b ("genalloc: use bitmap_find_next_zero_area").
