Is there a status document that lists - what SCSI drivers support write barriers (I'm interested in sym53c8xx_2 if that matters) - what IDE drivers support write barriers (VIA for AMD and Intel for PII/PIII/P4 chip sets here) - what file systems know how to utilize write barriers (other than reiserfs ;-) - what does "dummy ext3 patch" mean?
