This means that making the cache too large would decrease the performance. Therefore it was required to tune the size. Implement the name cache using a hash table. We use buckets of a fixed size. We approximate the least-frequently used cache algorithm by counting the number of lookups using saturating arithmetic in the two lowest bits of the pointer to the name. Using this strategy we achieve a constant worst-case lookup and insertion time. Since we are not bound by the size of the cache anymore, increase its size from 200 to 1024. * libdiskfs/name-cache.c: Implement the name cache using a hash table. (diskfs_enter_lookup_cache): Change accordingly. (diskfs_purge_lookup_cache): Likewise. (diskfs_check_lookup_cache): Likewise. Also, hard code a cache miss for the parent of the root directory and merge unlocking and releasing of node references. commit d0c565fc35e8dc3daa5fb6e9a514c34873e6b204 Author: Justus Winter <4win...@informatik.uni-hamburg.de> Date: Wed May 28 16:48:04 2014 +0200 libdiskfs: remove the statistics code from the name cache The current name cache lookup operation completes in O(n) time. This means that making the cache too large would decrease the performance. Therefore it was required to tune the size, hence the need for statistics. We will use a data structure with worst case constant lookup times in the future, removing the need to fine tune the cache size. * libdiskfs/name-cache.c: Remove the statistics code from the name cache. commit f6730b267a90ad73116e50b027e869cbe0b01211 Author: Justus Winter <4win...@informatik.uni-hamburg.de> Date: Sun May 18 14:06:30 2014 +0200 trans/fakeroot: use netfs_node_netnode instead of np->nn When using fat nodes, expressions of the form E->nn can be rewritten as netfs_node_netnode (E). This is much faster as it only involves a offset calculation. For reference, I used the following semantic patch to create the patch: @@ expression E; @@ - E->nn + netfs_node_netnode (E) * trans/fakeroot.c: Use netfs_node_netnode instead of np->nn. commit 6349d15921134adb4491eb9ce87720a0281a7bd6 Author: Justus Winter <4win...@informatik.uni-hamburg.de> Date: Sun May 18 13:45:14 2014 +0200 trans/fakeroot: use fat nodes to simplify the node cache Previously, fakeroot stored netnodes in the hash table. But we are not interested in a cache for netnodes, we need a node cache. So fakeroot kept pointers to the associated node object in each netnode object. Use fat netfs nodes, which combine node and netnode objects. * trans/fakeroot.c (struct netnode): Remove np. (idport_ihash): Fix ihash location pointer offset. (new_node): Allocate fat nodes, store the node pointer in the hash table. (netfs_node_norefs): Adjust accordingly.

Previously, both objects were allocated separatly, and a pointer from the node to the netnode provided a mapping from the former to the latter. Provide a function netfs_make_node_alloc that allocates both nodes in a contiguous region. This reduces the memory allocation overhead when creating nodes. It also makes the relation between node and netnode a simple offset calculation. Provide two functions to compu
