* performance/stat-prefetch: add "caller" arguement to sp_process_inode_ctx.Raghavendra G2009-12-061-23/+39
| | | | | | | | | | | - 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.

| | | | | | | | | | | | | | | | lookup on same path if one is in progress. - If current lookup (2) does not wait for completion of the lookup (1) which is in progress, there can be a race condition where (2) completes ahead of (1) and resuming all the waiting operations in the queue. When (1) returns, the original operation (eg., stat, chmod etc) might've already unwound and hence the frame would've been destroyed.

| | | | | | | | | | | | | | | | | | | | | | not the expected one. - cache creation is expensive operation. Also, cache will be freed in releasedir. Hence, just remove all entries from cache without freeing the cache. However this is not entirely true, since sp_cache_remove_entry frees the old table and reinitializes a new table if all entries are being removed. When rbtree based hash table provides an interface to remove all the entries, sp_cache_remove_entry should be modified not to destroy the table. - this patch also fixes a race condition wherein the cache being used in lookup getting freed in readdir if the offset is not equal to expected offset.
