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.

performance/stat-prefetch: fix memory leak.

2009-12-06T10:30:21+00:00

- rbt_hash_remove only removes entry from the hash table. It does not free
    the data.

performance/stat-prefetch: don't check whether previous lookups have been failed in sp_process_inode_ctx.

2009-12-05T12:21:29+00:00

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.

performance/stat-prefetch: add "caller" arguement to sp_process_inode_ctx.

2009-12-04T09:46:38+00:00

- since sp_process_inode_ctx is called by many fops, if the context is not
    set "caller" argument can be logged in log msgs to identify caller.

performance/stat-prefetch: dont check for inode context in fops like create, mkdir.

2009-12-04T09:46:26+00:00

- context will not be set as a fresh inode is passed in each of these calls.
    instead create a new context.
