2951 5846 d 15 h jermar /trunk/uspace/srv/fs/fat/ Add locks to FAT index structures, FAT in-core node structures. Add futex to
protect the list of free cached FAT in-core nodes. Make fat_node_get() and
fat_node_put() and some other functions aware of these new locks.		  
2945 5847 d 13 h jermar /trunk/uspace/srv/fs/fat/ Introduce a futex protecting the up_hash and ui_hash.  
2944 5847 d 14 h jermar /trunk/uspace/srv/fs/fat/ Introduce futex for protecting the list of unused structures in FAT server.  
2934 5848 d 16 h jermar /trunk/ Do not attempt to malloc() zero bytes of memory during VFS_READ at end of file.  
2910 5851 d 18 h jermar /trunk/uspace/srv/fs/fat/ Implement fat_node_put() and remove the node from the free node list when
bumping its refernce count from zero in fat_node_get().		  
2893 5852 d 23 h jermar /trunk/uspace/srv/fs/fat/ More bits of fat_node_get().
Still needs to do some locking.		  
2891 5855 d 13 h jermar /trunk/uspace/srv/fs/fat/ New first bits of fat_node_get().  
2890 5855 d 15 h jermar /trunk/uspace/srv/fs/fat/ Need a way to locate the FAT index structure by VFS index. Also fix code that
locates the FAT index structure by position in the file system namespace.		  
2889 5858 d 14 h jermar /trunk/uspace/srv/fs/fat/ Add hash table for used fat_idx_t structures and implement fat_idx_map().  
2884 5859 d 14 h jermar /trunk/uspace/srv/fs/fat/ merge vs. coalesce  
2881 5859 d 18 h jermar /trunk/uspace/srv/fs/fat/ Code for de/allocation of VFS indices for FAT.  
2879 5859 d 19 h jermar /trunk/uspace/lib/libc/include/libadt/ Add functions for inserting items before or after other items in a boubly-linked
circular lists.		  
2876 5859 d 22 h jermar /trunk/uspace/srv/fs/fat/ Add a dedicated source file for handling FAT indices.  
2864 5873 d 12 h jermar /trunk/uspace/srv/fs/fat/ Introduce the foundation for unique and stable FAT VFS node indices.

The first two reserved FAT entries are physically present in each FAT, so fix
the code to be aware of this.		  
2863 5873 d 23 h jermar /trunk/uspace/ Revert libfs node_get() API to a model without the parent node pointer
argument.		  
2861 5877 d 15 h cejka /trunk/ Used common macro for context saving on ppc64.  
2860 5878 d 15 h cejka /trunk/ Context handling unified for sparc64.  
2859 5879 d 5 h jermar /trunk/uspace/srv/fs/fat/ Add fat_block_get().  
2858 5879 d 7 h jermar /trunk/uspace/ libfs destroy operation should rather return an error code instead of a truth
value.		  
2857 5879 d 8 h jermar /trunk/uspace/ Add stubs for unimplemented FAT libfs operations.
