Re: device delete to get errors from the kernel

[Anand Jain <Anand.Jain@oracle.com>]

   Thanks for the comments. V2 is out. Here I followed
   the choice #1 as review suggested. which is to update
   the error code. However I have them in uapi/linux/btrfs.h
   (not in errno.h though I meant it to be there in the first
   place).

   pls do let me know your review comments.

Thanks, Anand
