Clang warns:
../drivers/block/xen-blkfront.c:1117:4: warning: misleading indentation;
statement is not part of the previous 'if' [-Wmisleading-indentation]
nr_parts = PARTS_PER_DISK;
^
../drivers/block/xen-blkfront.c:1115:3: note: previous statement is here

This is because there is a space at the beginning of this line; remove
it so that the indentation is consistent according to the Linux kernel
coding style and clang no longer warns.
While we are here, the previous line has some trailing whitespace; clean
that up as well.

While you're here, would you please also removing the single space
before the labels in this function?
In vim:
/^ [a-zA-Z]
turns up 5 labels with this.

That should probably be a separate patch since there are only two labels
in the function I am touching here. I'll whip up a v2 if the maintainers
want it though or I'll just draft a separate patch when I am done
addressing all of the misleading indentation warnings.
Thanks for the reply!

AFAIK those are intended to be there.
Having labels indented by a space makes diff not believe those are
function declarations. So a patching a function with a label won't show
the label, but the function in the diff block header.
