In my mind 'data' is for custom algorithms that could need additional data to perform the allocation (it is very similar to what is done in gen_pool_for_each_chunk function). In gen_pool_set_algo function I have test 'algo' just be sure that we alway have a valid algorithm function. gen_pool_alloc

[PATCH] genalloc: make possible to use a custom allocation algorithm

2012-09-07 Thread Benjamin Gaignard
From: Benjamin Gaignard This patch allow to use another algorithm than the default first-fit one. For example a custom algorithm could be used to manage alignment requirements. Add of best-fit algorithm function: most of the time best-fit is slower then first-fit but memory fragmentation is low
