We’re developing an SMR translation layer in a device mapper target, and we’d like to keep a lot of the complexity (recovery at startup, parts of the garbage collection algorithm) in user space.
I was wondering what people’s thoughts are on the best strategy for the user/kernel interface here? We’re currently doing something quite gross - using a /proc file with a simple protocol based on reading and writing fixed-sized binary messages. For our purposes this works fairly well, but clearly we need something cleaner if we want this to go anywhere. Thanks, .....................................................................
