Konrad Sztyber 085bfa0d13 lib/ftl: allocate separate memory for IO channels ... This is the first patch of a series that replaces single global write buffer with per-io_channel buffers. This change is intended to improve performance for multithreaded workloads. This patch changes the way the ftl_io_channels are allocated by only keeping an ftl_io_channel pointer inside spdk_io_channel's context. It allows for delaying IO channel destruction, which in turn allows the FTL to iterate over all exisiting IO channels without locking.
