commit d8458ae7013246b00e01464ef38b888483e6d47c Author: Matthew Dillon <dillon@apollo.backplane.com> Date: Thu Nov 11 10:15:46 2010 -0800 kernel - Make sure invalidated pages are unmapped in rare situation. * vfs_vmio_release() was ignoring pages busied by other MP users while releasing VM pages associated with the buffer cache. This could potentially lead to invalida pages remaining memory mapped. * Ensure that the released pages found to be in this state are still unmapped.
