the mapping is: VM_PAGER_OK 0 VM_PAGER_BAD <unused> VM_PAGER_FAIL <unused> VM_PAGER_PEND 0 (see below) VM_PAGER_ERROR EIO VM_PAGER_AGAIN EAGAIN VM_PAGER_UNLOCK EBUSY VM_PAGER_REFAULT ERESTART for async i/o requests, it used to be possible for the request to be convert to sync, and the pager would return VM_PAGER_OK or VM_PAGER_PEND to indicate whether the caller should perform post-i/o cleanup. this is no longer allowed; pagers must now return 0 to indicate that the async i/o was successfully started, and the caller never needs to worry about doing the post-i/o cleanup. |
