If I use CONFIG_BLK_DEV_PMEM=y (which is more convenient given how I launch my KVM test appliance), should I expect any problems? I assume that this won't detect any bugs caused by missing CLFLUSH instructions, but I assume that when using NVM as a block device, this isn't much of an issue, as long as we don't care about torn writes? (How using NVM with metdata checksums, or any checksums for that matter, seems to be an interesting question --- how do we recover from a checksum failure after a power failure?) - Ted -- To unsubscribe from this list: send the line "unsubscribe linux-ext4" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
