dm array: fix a reference counting bug in shadow_ablock

2013-12-20T15:49:04Z

commit ed9571f0cf1fe09d3506302610f3ccdfa1d22c4a upstream. An old array block could have its reference count decremented below zero when it is being replaced in the btree by a new array block. The fix is to increment the old ablock's reference count just before inserting a new ablock into the btree. Signed-off-by: Joe Thornber Signed-off-by: Mike Snitzer Signed-off-by: Greg Kroah-Hartman
