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