If the linux kernel is sending control messages in the wrong order, then it should cause corruption regardless of the number of unmapped blocks. -- Configure bugmail: https://bugzilla.kernel.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are watching the assignee of the bug.
