The patch was committed to head on March 11 and flagged for MFC, but it hasn't be merged to stable yet. I've been running this modification on 11.2-R and 12.0-R using the affected devices as system disks for a little over two months without issue. Can someone merge this into stable/11 and stable/12? It's important (to me, at least) that it make it into 11.3-R, and the slush for it isn't far off.
