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

2010-05-26T11:49:00+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.

stat-prefetch: Remove checks for loc->parent

2010-05-26T06:31:41+00:00

..because loc->parent can be NULL for the root inode.
Having this check makes sp return EINVAL on perfectly valid
fops.

cluster/afr: Check before accessing xattrs in data self heal.

2010-05-21T07:32:31+00:00

The lookup xattrs might be null, because a lookup might not have been issued during self heal,
especially if only data self heal is required.
