performance/io-cache: implement mknod fop.

2010-07-08T09:24:27+00:00

- mknod_cbk has to initialize ioc_inode context, since there is a possibility
    that open following immediately after mknod may not result in lookup before
    open fop.

performance/write-behind: explicitly enforce ordering of overlapping writes.

2010-07-02T11:44:46+00:00

- If there are non-contiguous offsets (offsets which do not start where
    previous write ended), wait for completion of previous writes to server,
    before sending new ones.
  - Send flush call to server only when all writes are completed.
  - If a file is opened with O_APPEND, at any point of time a maximum only one
    write call to server should be in transit. This is to avoid reordering of
    writes in the presence of afr which can result in data corruption.
    See bug #934 for more details.
