Subject[PATCH v12 5/5] xen/blkback: Consistently insert one empty line between functions
Date
From: SeongJae Park <sjpark@amazon.de>

The number of empty lines between functions in the xenbus.c is
inconsistent. This trivial style cleanup commit fixes the file to
consistently place only one empty line.
