| Description |
|
After patch http://review.whamcloud.com/980 is landed, direct IO will bypass CLIO so it's not necessary to maintain CPT_TRANSIENT pages any more. In this ticket, we'll get rid of CPT_TRANSIENT pages completely. Lloop device and liblustre will be reimplemented with new DIO interfaces. |

Even with 2.7.60 the CPT_TRANSIENT is still there. |

it looks like we still need the definition of CPT_TRANSIENT to distinguish DIO pages from cacheable pages. Therefore I'd like to close this ticket as 'Won't fix'. |
