2011-11-30erlang: Eliminate a clause in aa_mem_data/2 that can never matchBjörn Gustavsson
aa_mem_data/2 is only called by aa_mem_data/1 and itself. aa_mem_data/1 called with the argument 'notsup' will never call aa_mem_data/2. aa_mem_data/2 will only call itself with a #memory{} record as the first argument. QED. Noticed-by: Dialyzer.

2011-11-13Optimize memory allocationRickard Green
A number of memory allocation optimizations have been implemented. Most optimizations reduce contention caused by synchronization between threads during allocation and deallocation of memory. Most notably: * Synchronization of memory management in scheduler specific allocator instances has been rewritten to use lock-free synchronization. * Synchronization of memory management in scheduler specific pre-allocators has been rewritten to use lock-free synchronization. * The 'mseg_alloc' memory segment allocator now use scheduler specific instances instead of one instance. Apart from reducing contention this also ensures that memory allocators always create memory segments on the local NUMA node on a NUMA system.
2011-07-06Remove deprecated concat_binary/1Björn Gustavsson
concat_binary/1 was deprecated in R13B04, but already in the R10B-2 release, the documentation recommends using list_to_binary/1 instead.
