If we never inflict variable PAGE_CACHE_SIZE upon the kernel, these changes become pointless obfuscation. Let's put our horses ahead of our carts. We had a lengthy discussion about variable PAGE_CACHE_SIZE in which I pointed out that the performance benefits could be replicated in a manner which doesn't add complexity to core VFS and which provides immediate benefit to all filesystems without any need to alter them: populate contiguous pagecache pages with physically contiguous pages. I think the best way to proceed would be to investigate that _general_ optimisation and then, based upon the results of that work, decide whether further _specialised_ changes such as variable PAGE_CACHE_SIZE are needed, and if so, what they should be. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
