2953 5940 d 2 h jermar /trunk/uspace/srv/fs/fat/ Add synchronization to fat_match().  
2951 5940 d 3 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 5941 d 2 h jermar /trunk/uspace/srv/fs/fat/ Introduce a futex protecting the up_hash and ui_hash.  
2944 5941 d 2 h jermar /trunk/uspace/srv/fs/fat/ Introduce futex for protecting the list of unused structures in FAT server.  
2910 5945 d 7 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 5946 d 12 h jermar /trunk/uspace/srv/fs/fat/ More bits of fat_node_get().
Still needs to do some locking.		  
2891 5949 d 2 h jermar /trunk/uspace/srv/fs/fat/ New first bits of fat_node_get().  
2890 5949 d 4 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 5952 d 3 h jermar /trunk/uspace/srv/fs/fat/ Add hash table for used fat_idx_t structures and implement fat_idx_map().  
2884 5953 d 3 h jermar /trunk/uspace/srv/fs/fat/ merge vs. coalesce  
2881 5953 d 7 h jermar /trunk/uspace/srv/fs/fat/ Code for de/allocation of VFS indices for FAT.  
2876 5953 d 11 h jermar /trunk/uspace/srv/fs/fat/ Add a dedicated source file for handling FAT indices.  
2864 5967 d 1 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 5967 d 12 h jermar /trunk/uspace/ Revert libfs node_get() API to a model without the parent node pointer
argument.		  
2859 5972 d 17 h jermar /trunk/uspace/srv/fs/fat/ Add fat_block_get().  
2858 5972 d 20 h jermar /trunk/uspace/ libfs destroy operation should rather return an error code instead of a truth
value.		  
2857 5972 d 20 h jermar /trunk/uspace/ Add stubs for unimplemented FAT libfs operations.  
2856 5972 d 21 h jermar /trunk/uspace/srv/fs/fat/ Add a locking scheme for FAT in-core cache and nodes.  
2855 5972 d 22 h jermar /trunk/uspace/srv/fs/fat/ fat_node_put(). No locking so far.  
2852 5973 d 18 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 5975 d 0 h jermar /trunk/uspace/srv/fs/fat/ Add fat_has_children(). Alse assume that fat_block_get() can never return NULL.  
2844 5975 d 1 h jermar /trunk/uspace/ Add fat_root_get() and fat_plb_get_char().  
2843 5975 d 2 h jermar /trunk/uspace/srv/fs/fat/ Somewhat complete implementation of fat_node_get().  
2831 5977 d 18 h jermar /trunk/uspace/ Commit progress on the FAT file system server implementation.  
2828 5978 d 22 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 5979 d 22 h jermar /trunk/uspace/srv/fs/fat/ Introduce and also use the foundation of block cache API in FAT's match
operation.		  
2798 5984 d 3 h jermar /trunk/uspace/ Replace all endian.h in uspace with a copy of the kernel's respective byteorder.h.  
2796 5985 d 3 h jermar /trunk/uspace/srv/fs/fat/ Convert FAT on-disk metadata from little-endian to native representation.  
2793 5985 d 4 h jermar /trunk/uspace/srv/fs/fat/ First untested bits of FAT lookup support.  
2792 5985 d 4 h jermar /trunk/uspace/ libfs' node_get() operation does not need the file system handle.  
2791 5988 d 1 h jermar /trunk/uspace/ Make libfs_lookup() more generic.  
2789 5990 d 15 h jermar /trunk/uspace/srv/fs/fat/ Fix FAT boot sector definition and introduce the FAT in-core node type.  
2770 6007 d 3 h jermar /trunk/uspace/ Introduce fs_handle_t, dev_handle_t and fs_index_t.  
2763 6009 d 6 h jermar /trunk/uspace/ Support for rename().  
2760 6012 d 1 h jermar /trunk/uspace/ Support for multiple TMPFS node names.  
2758 6013 d 1 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 6013 d 3 h jermar /trunk/uspace/srv/fs/tmpfs/ Set the TMPFS root node's link count to 1.  
2756 6013 d 4 h jermar /trunk/uspace/srv/fs/tmpfs/ Introduce real link counts for TMPFS.  
2747 6020 d 1 h jermar /trunk/uspace/ Move the core lookup logic from TMPFS to libfs.  
2742 6022 d 1 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().
