| | | | | | | | | | | | | | | | | - 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.

| | | | | | | | | | | | | | | | | | | | failed in sp_process_inode_ctx. We need this patch for following reasons: 1. The inode used in the successful lookup call may not be the one passed to fops operating on path. This may happen, if revalidate of inode is failed, but the lookup itself succeeds (in case of reavalidate failures, fuse sends a fresh lookup using new inode) and since inode_link, if there is an inode already associated with a path retains it. 2. Only fops that "wait" in stat-prefetch for a lookup which is already in progress, need to check for the result of the lookup they are waiting on, before resuming and sp_process_inode_ctx is _not_ used in such contexts.
