From 8b6bf747d70e5bac1a34c8fd773230e1cfdd7546 Mon Sep 17 00:00:00 2001 From: Konrad Rzeszutek Wilk Date: Wed, 20 Apr 2011 11:50:43 -0400 Subject: xen/blkback: Prefix exposed functions with xen_ And also shorten the name if it has blkback to blkbk. This results in the symbol table (if compiled in the kernel) to be much shorter, prettier, and also easier to search for.
