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 | |||
