    Description

      The first time "lfs setstripe" is used after mount, there is always a message printed on the console:

      Lustre: lfs: using old ioctl(LL_IOC_LOV_GETSTRIPE) on [0x200000402:0x2:0x0], use llapi_layout_get_by_path()
      

      We shouldn't be using an old interface that prints a warning message for a standard command.

      I haven't totally tracked down the callpath(s) that generate this message, but it is probably from the ll_file_getstripe() at the end of ll_lov_setstripe().

      It may be enough to not print the message if size != 0, and pass the size of the ioctl buffer by getting it via _IOC_SIZE(cmd) when LL_IOC_LOV_GETSTRIPE_NEW is called, and start using LL_IOC_LOV_GETSTRIPE_NEW from lfs.c?
