I had been applied, but had to be updated further, see https://git.kernel.org/cgit/linux/kernel/git/mason/btrfs-progs.git/commit/?id=7b668965f0cf3fb8632c505a7a011189ee1a5a8e " Replacing memcpy with memmove does't work - gcc treats memmove the same way it treats memcpy. This patch brings in {get|put}_unaligned_le{16|32|64} (using the packed struct method), and uses them in the failing get/set calls. On architectures where unaligned accesses are cheap, these unaligned macros should be optimized out by the compiler. " What's still missing is get_unaligned_* in the BTRFS_SETGET_STACK_FUNCS macros. david -- To unsubscribe from this list: send the line "unsubscribe linux-btrfs" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
