One (somewhat obscure) regression will be that you won't be able to recover from uncorrected memory errors in the buffer cache anymore. Previously memory_failure() could just drop it transparently when that happens and the page is currently not used. This is usually only a problem if there's significant memory tied up in it. -Andi -- ak@linux.intel.com -- Speaking for myself only _______________________________________________ xfs mailing list xfs@oss.sgi.com http://oss.sgi.com/mailman/listinfo/xfs
