- * API in libglusterfsclient only set the offset. The consequence is that when
- * libgf_dcache_readdir finds that the offset presented to it, is not
- * the same as the offset of the previous dirent returned by dcache (..stored
- * in struct direntcache->prev_off..), it realises that a non-sequential
- * directory read is in progress and returns 0 to signify that the cache is
- * not valid.
- * This could be made a bit more intelligent by using a data structure like
- * a hash-table or a balanced binary tree that allows us to search for the
- * existence of particular offsets in the cache without performing a list or
- * array traversal.
- * Dont use a simple binary search tree because
- * there is no guarantee that offsets in a sequential reading of the directory
- * will be just random integers. If for some reason they are sequential, a BST
- * will end up becoming a list.
