2890 5904 d 21 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 5907 d 20 h jermar /trunk/uspace/srv/fs/fat/ Add hash table for used fat_idx_t structures and implement fat_idx_map().  
2884 5908 d 20 h jermar /trunk/uspace/srv/fs/fat/ merge vs. coalesce  
2881 5909 d 0 h jermar /trunk/uspace/srv/fs/fat/ Code for de/allocation of VFS indices for FAT.  
2876 5909 d 4 h jermar /trunk/uspace/srv/fs/fat/ Add a dedicated source file for handling FAT indices.  
2864 5922 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 5923 d 5 h jermar /trunk/uspace/ Revert libfs node_get() API to a model without the parent node pointer
argument.		  
2859 5928 d 10 h jermar /trunk/uspace/srv/fs/fat/ Add fat_block_get().  
2858 5928 d 13 h jermar /trunk/uspace/ libfs destroy operation should rather return an error code instead of a truth
value.		  
2857 5928 d 14 h jermar /trunk/uspace/ Add stubs for unimplemented FAT libfs operations.  
2856 5928 d 14 h jermar /trunk/uspace/srv/fs/fat/ Add a locking scheme for FAT in-core cache and nodes.  
2855 5928 d 15 h jermar /trunk/uspace/srv/fs/fat/ fat_node_put(). No locking so far.  
2852 5929 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 5930 d 17 h jermar /trunk/uspace/srv/fs/fat/ Add fat_has_children(). Alse assume that fat_block_get() can never return NULL.  
2844 5930 d 18 h jermar /trunk/uspace/ Add fat_root_get() and fat_plb_get_char().  
2843 5930 d 19 h jermar /trunk/uspace/srv/fs/fat/ Somewhat complete implementation of fat_node_get().  
2831 5933 d 11 h jermar /trunk/uspace/ Commit progress on the FAT file system server implementation.  
2828 5934 d 16 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 5935 d 15 h jermar /trunk/uspace/srv/fs/fat/ Introduce and also use the foundation of block cache API in FAT's match
operation.		  
2821 5935 d 15 h jermar /trunk/uspace/srv/vfs/ Update comment.  
2798 5939 d 20 h jermar /trunk/uspace/ Replace all endian.h in uspace with a copy of the kernel's respective byteorder.h.  
2796 5940 d 20 h jermar /trunk/uspace/srv/fs/fat/ Convert FAT on-disk metadata from little-endian to native representation.  
2793 5940 d 21 h jermar /trunk/uspace/srv/fs/fat/ First untested bits of FAT lookup support.  
2792 5940 d 21 h jermar /trunk/uspace/ libfs' node_get() operation does not need the file system handle.  
2791 5943 d 18 h jermar /trunk/uspace/ Make libfs_lookup() more generic.  
2789 5946 d 8 h jermar /trunk/uspace/srv/fs/fat/ Fix FAT boot sector definition and introduce the FAT in-core node type.  
2788 5946 d 9 h jermar /trunk/uspace/ Return EBUSY if trying to mount something over an already mounted root FS.
(Contributed by Tim Post)		  
2770 5962 d 20 h jermar /trunk/uspace/ Introduce fs_handle_t, dev_handle_t and fs_index_t.  
2769 5963 d 19 h jermar /trunk/uspace/srv/vfs/ VFS index needs to be treated as uint64_t.  
2768 5963 d 21 h jermar /trunk/uspace/srv/vfs/ Fibril serialization is required when two file systems register contemporarily.  
2766 5964 d 21 h jermar /trunk/uspace/srv/vfs/ Grab the nodes_futex when manipulating node link counts in rename() and
_unlink().

Fix VFS futex definitions and declarations by replacing atomic_t by futex_t.		  
2763 5964 d 23 h jermar /trunk/uspace/ Support for rename().  
2760 5967 d 18 h jermar /trunk/uspace/ Support for multiple TMPFS node names.  
2758 5968 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 5968 d 20 h jermar /trunk/uspace/srv/fs/tmpfs/ Set the TMPFS root node's link count to 1.  
2756 5968 d 21 h jermar /trunk/uspace/srv/fs/tmpfs/ Introduce real link counts for TMPFS.  
2753 5971 d 19 h jermar /trunk/uspace/ Move canonify() to libc so that it can be used also on the libc side.  
2752 5972 d 2 h jermar /trunk/uspace/srv/vfs/ Make VFS canonify path names on lookup.  
2751 5973 d 0 h jermar /trunk/uspace/ Add canonify() for file system path canonization.
Not yet used by VFS.		  
2749 5974 d 19 h jermar /trunk/uspace/srv/vfs/ contents_rwlock should not be acquired as a futex but rather as a rwlock.
