	Replace the hand-written hash table in the node cache with libihash. Libihash is a self-tuning hash table, whereas the previous code used a fixed number of buckets. * libdiskfs/Makefile (HURDLIBS): Link to `ihash'. * libdiskfs/diskfs.h (struct node): Remove bucket list, add slot pointer. * libdiskfs/node-cache.c (nodecache): New ihash table replacing the old `nodehash'. (lookup): Drop function. (diskfs_cached_lookup_context): Adapt accordingly. (diskfs_cached_ifind): Likewise. (diskfs_try_dropping_softrefs): Likewise. (diskfs_node_iterate): Likewise.

	* libdiskfs/node-cache.c (diskfs_node_iterate): Do not print a message on ENOMEM.
2015-04-17	libdiskfs: implement a node cache	Justus Winter
	Previously, all users of libdiskfs implemented a node cache on their own. Move the node cache from ext2fs into libdiskfs. We preserve the previous API by marking all functions that we pull from ext2fs as weak, so that users like tmpfs can still implement their own node cache. * ext2fs/dir.c (diskfs_lookup_hard): Adjust accordingly. * ext2fs/ext2fs.c (main): Don't call `inode_init'. * ext2fs/ext2fs.h (struct disknode): Drop `hnext', `hprevp'. * ext2fs/inode.c: Move the node cache into diskfs. (diskfs_user_make_node): New function. (diskfs_try_dropping_softrefs): Rename to `diskfs_user_try_dropping_softrefs'. (read_node): Rename to `diskfs_user_read_node'. Also move a chunk of code dealing with generations from `diskfs_cached_lookup' here. * libdiskfs/Makefile (OTHERSRCS): Add `node-cache.c'. * libdiskfs/diskfs.h (struct node): Add `hnext', `hprevp'. Amend existing comments, add forward declarations. * libdiskfs/node-cache.c: New file.
