2864 5952 d 8 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 5952 d 19 h jermar /trunk/uspace/ Revert libfs node_get() API to a model without the parent node pointer
argument.		  
2859 5958 d 1 h jermar /trunk/uspace/srv/fs/fat/ Add fat_block_get().  
2858 5958 d 4 h jermar /trunk/uspace/ libfs destroy operation should rather return an error code instead of a truth
value.		  
2857 5958 d 4 h jermar /trunk/uspace/ Add stubs for unimplemented FAT libfs operations.  
2856 5958 d 4 h jermar /trunk/uspace/srv/fs/fat/ Add a locking scheme for FAT in-core cache and nodes.  
2855 5958 d 5 h jermar /trunk/uspace/srv/fs/fat/ fat_node_put(). No locking so far.  
2852 5959 d 2 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 5960 d 8 h jermar /trunk/uspace/srv/fs/fat/ Add fat_has_children(). Alse assume that fat_block_get() can never return NULL.  
2844 5960 d 8 h jermar /trunk/uspace/ Add fat_root_get() and fat_plb_get_char().  
2843 5960 d 9 h jermar /trunk/uspace/srv/fs/fat/ Somewhat complete implementation of fat_node_get().  
2831 5963 d 2 h jermar /trunk/uspace/ Commit progress on the FAT file system server implementation.  
2828 5964 d 6 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 5965 d 6 h jermar /trunk/uspace/srv/fs/fat/ Introduce and also use the foundation of block cache API in FAT's match
operation.		  
2798 5969 d 10 h jermar /trunk/uspace/ Replace all endian.h in uspace with a copy of the kernel's respective byteorder.h.  
2796 5970 d 10 h jermar /trunk/uspace/srv/fs/fat/ Convert FAT on-disk metadata from little-endian to native representation.  
2793 5970 d 11 h jermar /trunk/uspace/srv/fs/fat/ First untested bits of FAT lookup support.  
2792 5970 d 11 h jermar /trunk/uspace/ libfs' node_get() operation does not need the file system handle.  
2791 5973 d 8 h jermar /trunk/uspace/ Make libfs_lookup() more generic.  
2789 5975 d 22 h jermar /trunk/uspace/srv/fs/fat/ Fix FAT boot sector definition and introduce the FAT in-core node type.  
2770 5992 d 10 h jermar /trunk/uspace/ Introduce fs_handle_t, dev_handle_t and fs_index_t.  
2763 5994 d 14 h jermar /trunk/uspace/ Support for rename().  
2760 5997 d 8 h jermar /trunk/uspace/ Support for multiple TMPFS node names.  
2758 5998 d 9 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 5998 d 10 h jermar /trunk/uspace/srv/fs/tmpfs/ Set the TMPFS root node's link count to 1.  
2756 5998 d 11 h jermar /trunk/uspace/srv/fs/tmpfs/ Introduce real link counts for TMPFS.  
2747 6005 d 8 h jermar /trunk/uspace/ Move the core lookup logic from TMPFS to libfs.  
2742 6007 d 8 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 6013 d 9 h jermar /trunk/uspace/srv/fs/tmpfs/ Remove duplicate initialization.  
2736 6015 d 11 h jermar /trunk/uspace/srv/fs/tmpfs/ Unlink a TMPFS node more thoroughly.  
2735 6015 d 14 h jermar /trunk/uspace/ Support for rmdir(), unlink() and the respective VFS operations.  
2733 6015 d 16 h jermar /trunk/uspace/ Add TMPFS support for destroying leaf links in the file system namespace.  
2732 6015 d 17 h jermar /trunk/uspace/srv/fs/tmpfs/ When freeing up a TMPFS node, it should also be removed from the dentries hash table.  
2731 6015 d 17 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 6016 d 19 h jermar /trunk/uspace/srv/ Introduce the notion of VFS node link counts.  
2728 6021 d 9 h jermar /trunk/uspace/srv/fs/tmpfs/ Descend vs. descent.  
2711 6036 d 12 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 6036 d 12 h jermar /trunk/uspace/ VFS_WRITE and tmpfs_write fixes.  
2707 6036 d 16 h jermar /trunk/uspace/ Support for mkdir().  
2706 6036 d 20 h jermar /trunk/uspace/srv/fs/tmpfs/ Move handling of the miss on excessive components out of the main loop in
tmpfs_lookup.
