2944 5991 d 16 h jermar /trunk/uspace/srv/fs/fat/ Introduce futex for protecting the list of unused structures in FAT server.  
2910 5995 d 21 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 5997 d 2 h jermar /trunk/uspace/srv/fs/fat/ More bits of fat_node_get().
Still needs to do some locking.		  
2891 5999 d 16 h jermar /trunk/uspace/srv/fs/fat/ New first bits of fat_node_get().  
2890 5999 d 18 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 6002 d 17 h jermar /trunk/uspace/srv/fs/fat/ Add hash table for used fat_idx_t structures and implement fat_idx_map().  
2884 6003 d 17 h jermar /trunk/uspace/srv/fs/fat/ merge vs. coalesce  
2881 6003 d 21 h jermar /trunk/uspace/srv/fs/fat/ Code for de/allocation of VFS indices for FAT.  
2876 6004 d 1 h jermar /trunk/uspace/srv/fs/fat/ Add a dedicated source file for handling FAT indices.  
2864 6017 d 15 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 6018 d 2 h jermar /trunk/uspace/ Revert libfs node_get() API to a model without the parent node pointer
argument.		  
2859 6023 d 7 h jermar /trunk/uspace/srv/fs/fat/ Add fat_block_get().  
2858 6023 d 10 h jermar /trunk/uspace/ libfs destroy operation should rather return an error code instead of a truth
value.		  
2857 6023 d 10 h jermar /trunk/uspace/ Add stubs for unimplemented FAT libfs operations.  
2856 6023 d 11 h jermar /trunk/uspace/srv/fs/fat/ Add a locking scheme for FAT in-core cache and nodes.  
2855 6023 d 12 h jermar /trunk/uspace/srv/fs/fat/ fat_node_put(). No locking so far.  
2852 6024 d 8 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 6025 d 14 h jermar /trunk/uspace/srv/fs/fat/ Add fat_has_children(). Alse assume that fat_block_get() can never return NULL.  
2844 6025 d 15 h jermar /trunk/uspace/ Add fat_root_get() and fat_plb_get_char().  
2843 6025 d 16 h jermar /trunk/uspace/srv/fs/fat/ Somewhat complete implementation of fat_node_get().  
2831 6028 d 8 h jermar /trunk/uspace/ Commit progress on the FAT file system server implementation.  
2828 6029 d 12 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 6030 d 12 h jermar /trunk/uspace/srv/fs/fat/ Introduce and also use the foundation of block cache API in FAT's match
operation.		  
2798 6034 d 17 h jermar /trunk/uspace/ Replace all endian.h in uspace with a copy of the kernel's respective byteorder.h.  
2796 6035 d 17 h jermar /trunk/uspace/srv/fs/fat/ Convert FAT on-disk metadata from little-endian to native representation.  
2793 6035 d 18 h jermar /trunk/uspace/srv/fs/fat/ First untested bits of FAT lookup support.  
2792 6035 d 18 h jermar /trunk/uspace/ libfs' node_get() operation does not need the file system handle.  
2791 6038 d 15 h jermar /trunk/uspace/ Make libfs_lookup() more generic.  
2789 6041 d 5 h jermar /trunk/uspace/srv/fs/fat/ Fix FAT boot sector definition and introduce the FAT in-core node type.  
2770 6057 d 17 h jermar /trunk/uspace/ Introduce fs_handle_t, dev_handle_t and fs_index_t.  
2763 6059 d 20 h jermar /trunk/uspace/ Support for rename().  
2760 6062 d 15 h jermar /trunk/uspace/ Support for multiple TMPFS node names.  
2758 6063 d 15 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 6063 d 17 h jermar /trunk/uspace/srv/fs/tmpfs/ Set the TMPFS root node's link count to 1.  
2756 6063 d 18 h jermar /trunk/uspace/srv/fs/tmpfs/ Introduce real link counts for TMPFS.  
2747 6070 d 15 h jermar /trunk/uspace/ Move the core lookup logic from TMPFS to libfs.  
2742 6072 d 15 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().		  
2739 6078 d 15 h jermar /trunk/uspace/srv/fs/tmpfs/ Remove duplicate initialization.  
2736 6080 d 17 h jermar /trunk/uspace/srv/fs/tmpfs/ Unlink a TMPFS node more thoroughly.  
2735 6080 d 21 h jermar /trunk/uspace/ Support for rmdir(), unlink() and the respective VFS operations.
