What makes you think KMEM_CACHE is new? It was added to the kernel in 2007 The vast majority of the kernel is still using kmem_cache_create(), not the weird, shouty macro that doesn't actually tell us what it is doing with said kmem_cache...... Up until now I've chosen not switch XFS to use it because many of the slab caches we use in XFS are not just "default" slab caches. IOWs, we still have to use kmem_cache_create() for a lot of the caches we create, so we may as well use kmem_cache_create() for all of them rather than have to go look up what KMEM_CACHE() translates to every time we are looking at how slab caches are created. Also, if you are going to change simple API stuff like this in XFS, please do all the conversions in a single patch. It takes much less time and resources to review and merge a single patch compared to a couple of dozen independent one line patches... -Dave. -- Dave Chinner david@xxxxxxxxxxxxx
