2953 5975 d 4 h jermar /trunk/uspace/srv/fs/fat/ Add synchronization to fat_match().  
2951 5975 d 5 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 5976 d 4 h jermar /trunk/uspace/srv/fs/fat/ Introduce a futex protecting the up_hash and ui_hash.  
2944 5976 d 4 h jermar /trunk/uspace/srv/fs/fat/ Introduce futex for protecting the list of unused structures in FAT server.  
2910 5980 d 9 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 5981 d 14 h jermar /trunk/uspace/srv/fs/fat/ More bits of fat_node_get().
Still needs to do some locking.		  
2891 5984 d 4 h jermar /trunk/uspace/srv/fs/fat/ New first bits of fat_node_get().  
2890 5984 d 6 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 5987 d 5 h jermar /trunk/uspace/srv/fs/fat/ Add hash table for used fat_idx_t structures and implement fat_idx_map().  
2884 5988 d 5 h jermar /trunk/uspace/srv/fs/fat/ merge vs. coalesce  
2881 5988 d 9 h jermar /trunk/uspace/srv/fs/fat/ Code for de/allocation of VFS indices for FAT.  
2876 5988 d 13 h jermar /trunk/uspace/srv/fs/fat/ Add a dedicated source file for handling FAT indices.  
2864 6002 d 3 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 6002 d 14 h jermar /trunk/uspace/ Revert libfs node_get() API to a model without the parent node pointer
argument.		  
2859 6007 d 19 h jermar /trunk/uspace/srv/fs/fat/ Add fat_block_get().  
2858 6007 d 22 h jermar /trunk/uspace/ libfs destroy operation should rather return an error code instead of a truth
value.		  
2857 6007 d 22 h jermar /trunk/uspace/ Add stubs for unimplemented FAT libfs operations.  
2856 6007 d 23 h jermar /trunk/uspace/srv/fs/fat/ Add a locking scheme for FAT in-core cache and nodes.  
2855 6008 d 0 h jermar /trunk/uspace/srv/fs/fat/ fat_node_put(). No locking so far.  
2852 6008 d 20 h jermar /trunk/uspace/ Add node_put() to libfs operations and instrument libfs_lookup() to use it at
appropriate places.
Add node_put() to libfs operations and instrument libfs_lookup() to use it at
appropriate places.
Add node_put() to libfs operations and instrument libfs_lookup() to use it at
appropriate places.
Add node_put() to libfs operations and instrument libfs_lookup() to use it at
appropriate places.
Add node_put() to libfs operations and instrument libfs_lookup() to use it at
appropriate places.
Add node_put() to libfs operations and instrument libfs_lookup() to use it at
appropriate places.		  
2845 6010 d 2 h jermar /trunk/uspace/srv/fs/fat/ Add fat_has_children(). Alse assume that fat_block_get() can never return NULL.  
2844 6010 d 3 h jermar /trunk/uspace/ Add fat_root_get() and fat_plb_get_char().  
2843 6010 d 4 h jermar /trunk/uspace/srv/fs/fat/ Somewhat complete implementation of fat_node_get().  
2831 6012 d 20 h jermar /trunk/uspace/ Commit progress on the FAT file system server implementation.  
2828 6014 d 0 h jermar /trunk/uspace/srv/fs/fat/ BPS read from FAT bootsector is little-endian. It must converted to host
endianity before being used.		  
2822 6015 d 0 h jermar /trunk/uspace/srv/fs/fat/ Introduce and also use the foundation of block cache API in FAT's match
operation.		  
2798 6019 d 5 h jermar /trunk/uspace/ Replace all endian.h in uspace with a copy of the kernel's respective byteorder.h.  
2796 6020 d 5 h jermar /trunk/uspace/srv/fs/fat/ Convert FAT on-disk metadata from little-endian to native representation.  
2793 6020 d 6 h jermar /trunk/uspace/srv/fs/fat/ First untested bits of FAT lookup support.  
2792 6020 d 6 h jermar /trunk/uspace/ libfs' node_get() operation does not need the file system handle.  
2791 6023 d 3 h jermar /trunk/uspace/ Make libfs_lookup() more generic.  
2789 6025 d 17 h jermar /trunk/uspace/srv/fs/fat/ Fix FAT boot sector definition and introduce the FAT in-core node type.  
2770 6042 d 5 h jermar /trunk/uspace/ Introduce fs_handle_t, dev_handle_t and fs_index_t.  
2763 6044 d 8 h jermar /trunk/uspace/ Support for rename().  
2760 6047 d 3 h jermar /trunk/uspace/ Support for multiple TMPFS node names.  
2758 6048 d 3 h jermar /trunk/uspace/ No need to keep the parent pointer in the TMPFS node. Moreover, other file
systems won't have it either. Finally, if TMPFS is to support hardlinks, there
can be multiple parents.		  
2757 6048 d 5 h jermar /trunk/uspace/srv/fs/tmpfs/ Set the TMPFS root node's link count to 1.  
2756 6048 d 6 h jermar /trunk/uspace/srv/fs/tmpfs/ Introduce real link counts for TMPFS.  
2747 6055 d 3 h jermar /trunk/uspace/ Move the core lookup logic from TMPFS to libfs.  
2742 6057 d 3 h jermar /trunk/uspace/srv/ Separate creation of a TMPFS node and its linking in the file system name space.
Rename VFS_FREE to VFS_DESTROY and destroy_node() to unlink_node().
