| 507 | * What an NFS client should do upon close after writing is a debatable issue. |

| 509 | * two reasons: |
| 510 | * 1 - So that any write errors may be reported back to the client process |
| 511 | * doing the close system call. By far the two most likely errors are |
| 512 | * NFSERR_NOSPC and NFSERR_DQUOT to indicate space allocation failure. |
| 513 | * 2 - To put a worst case upper bound on cache inconsistency between |
| 514 | * multiple clients for the file. |
| 515 | * There is also a consistency problem for Version 2 of the protocol w.r.t. |
| 516 | * not being able to tell if other clients are writing a file concurrently, |
| 517 | * since there is no way of knowing if the changed modify time in the reply |
| 518 | * is only due to the write for this client. |
| 519 | * (NFS Version 3 provides weak cache consistency data in the reply that |
| 520 | * should be sufficient to detect and handle this case.) |
| 521 | * |
| 522 | * The current code does the following: |
| 523 | * for NFS Version 2 - play it safe and flush/invalidate all dirty buffers |
| 524 | * for NFS Version 3 - flush dirty buffers to the server but don't invalidate |
| 525 | * or commit them (this satisfies 1 and 2 except for the |
| 526 | * case where the server crashes after this close but |
| 527 | * before the commit RPC, which is felt to be "good |
| 528 | * enough". Changing the last argument to nfs_flush() to |
| 529 | * a 1 would force a commit operation, if it is felt a |
