2013-03-04xen-blkback: do not leak mode propertyJan Beulich
commit 9d092603cc306ee6edfe917bf9ab8beb5f32d7bc upstream. "be->mode" is obtained from xenbus_read(), which does a kmalloc() for the message body. The short string is never released, so do it along with freeing "be" itself, and make sure the string isn't kept when backend_changed() doesn't complete successfully (which made it desirable to slightly re-structure that function, so that the error cleanup can be done in one place).

2011-05-05xen/blkback: Add support for BLKIF_OP_FLUSH_DISKCACHE and drop ↵Konrad Rzeszutek Wilk
BLKIF_OP_WRITE_BARRIER. We drop the support for 'feature-barrier' and add in the support for the 'feature-flush-cache' if the real backend storage supports flushing. Signed-off-by: Konrad Rzeszutek Wilk <konrad.wilk@oracle.com>
2011-04-20xen/blkback: Prefix exposed functions with xen_Konrad Rzeszutek Wilk
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. Signed-off-by: Konrad Rzeszutek Wilk <konrad.wilk@oracle.com>

Daniel Stodden suggested to eliminate vbd.c and interface.c, inlining the critical bits where they belong, respectively. Leaving only blkback.c for the data- and xenbus.c for the control path.
