2864 5929 d 18 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 5930 d 5 h jermar /trunk/uspace/ Revert libfs node_get() API to a model without the parent node pointer
argument.		  
2859 5935 d 10 h jermar /trunk/uspace/srv/fs/fat/ Add fat_block_get().  
2858 5935 d 13 h jermar /trunk/uspace/ libfs destroy operation should rather return an error code instead of a truth
value.		  
2857 5935 d 13 h jermar /trunk/uspace/ Add stubs for unimplemented FAT libfs operations.  
2856 5935 d 14 h jermar /trunk/uspace/srv/fs/fat/ Add a locking scheme for FAT in-core cache and nodes.  
2855 5935 d 14 h jermar /trunk/uspace/srv/fs/fat/ fat_node_put(). No locking so far.  
2852 5936 d 11 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 5937 d 17 h jermar /trunk/uspace/srv/fs/fat/ Add fat_has_children(). Alse assume that fat_block_get() can never return NULL.  
2844 5937 d 18 h jermar /trunk/uspace/ Add fat_root_get() and fat_plb_get_char().  
2843 5937 d 19 h jermar /trunk/uspace/srv/fs/fat/ Somewhat complete implementation of fat_node_get().  
2831 5940 d 11 h jermar /trunk/uspace/ Commit progress on the FAT file system server implementation.  
2828 5941 d 15 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 5942 d 15 h jermar /trunk/uspace/srv/fs/fat/ Introduce and also use the foundation of block cache API in FAT's match
operation.		  
2798 5946 d 20 h jermar /trunk/uspace/ Replace all endian.h in uspace with a copy of the kernel's respective byteorder.h.  
2796 5947 d 20 h jermar /trunk/uspace/srv/fs/fat/ Convert FAT on-disk metadata from little-endian to native representation.  
2793 5947 d 21 h jermar /trunk/uspace/srv/fs/fat/ First untested bits of FAT lookup support.  
2792 5947 d 21 h jermar /trunk/uspace/ libfs' node_get() operation does not need the file system handle.  
2791 5950 d 18 h jermar /trunk/uspace/ Make libfs_lookup() more generic.  
2789 5953 d 8 h jermar /trunk/uspace/srv/fs/fat/ Fix FAT boot sector definition and introduce the FAT in-core node type.  
2770 5969 d 20 h jermar /trunk/uspace/ Introduce fs_handle_t, dev_handle_t and fs_index_t.  
2763 5971 d 23 h jermar /trunk/uspace/ Support for rename().  
2760 5974 d 18 h jermar /trunk/uspace/ Support for multiple TMPFS node names.  
2758 5975 d 18 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 5975 d 20 h jermar /trunk/uspace/srv/fs/tmpfs/ Set the TMPFS root node's link count to 1.  
2756 5975 d 21 h jermar /trunk/uspace/srv/fs/tmpfs/ Introduce real link counts for TMPFS.  
2747 5982 d 18 h jermar /trunk/uspace/ Move the core lookup logic from TMPFS to libfs.  
2742 5984 d 18 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 5990 d 18 h jermar /trunk/uspace/srv/fs/tmpfs/ Remove duplicate initialization.  
2736 5992 d 20 h jermar /trunk/uspace/srv/fs/tmpfs/ Unlink a TMPFS node more thoroughly.  
2735 5993 d 0 h jermar /trunk/uspace/ Support for rmdir(), unlink() and the respective VFS operations.  
2733 5993 d 2 h jermar /trunk/uspace/ Add TMPFS support for destroying leaf links in the file system namespace.  
2732 5993 d 2 h jermar /trunk/uspace/srv/fs/tmpfs/ When freeing up a TMPFS node, it should also be removed from the dentries hash table.  
2731 5993 d 3 h jermar /trunk/uspace/srv/ Add the VFS_FREE operation. This operation frees up whatever resources used by
a file system node for which there is no name (i.e. an unlinked node).

Cleanup VFS operations enums and remove unneeded VFS operations.		  
2730 5994 d 5 h jermar /trunk/uspace/srv/ Introduce the notion of VFS node link counts.  
2728 5998 d 18 h jermar /trunk/uspace/srv/fs/tmpfs/ Descend vs. descent.  
2711 6013 d 21 h jermar /trunk/uspace/ Remove the debugging hack from tmpfs_init(), which created several files and
directories on the filesystem. TMPFS is now self-sufficient enough to be able
to create its content via the standard VFS interface.		  
2710 6013 d 21 h jermar /trunk/uspace/ VFS_WRITE and tmpfs_write fixes.  
2707 6014 d 1 h jermar /trunk/uspace/ Support for mkdir().  
2706 6014 d 6 h jermar /trunk/uspace/srv/fs/tmpfs/ Move handling of the miss on excessive components out of the main loop in
tmpfs_lookup.
