2876 5920 d 23 h jermar /trunk/uspace/srv/fs/fat/ Add a dedicated source file for handling FAT indices.  
2864 5934 d 13 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 5935 d 1 h jermar /trunk/uspace/ Revert libfs node_get() API to a model without the parent node pointer
argument.		  
2859 5940 d 6 h jermar /trunk/uspace/srv/fs/fat/ Add fat_block_get().  
2858 5940 d 9 h jermar /trunk/uspace/ libfs destroy operation should rather return an error code instead of a truth
value.		  
2857 5940 d 9 h jermar /trunk/uspace/ Add stubs for unimplemented FAT libfs operations.  
2856 5940 d 9 h jermar /trunk/uspace/srv/fs/fat/ Add a locking scheme for FAT in-core cache and nodes.  
2855 5940 d 10 h jermar /trunk/uspace/srv/fs/fat/ fat_node_put(). No locking so far.  
2852 5941 d 7 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 5942 d 13 h jermar /trunk/uspace/srv/fs/fat/ Add fat_has_children(). Alse assume that fat_block_get() can never return NULL.  
2844 5942 d 13 h jermar /trunk/uspace/ Add fat_root_get() and fat_plb_get_char().  
2843 5942 d 14 h jermar /trunk/uspace/srv/fs/fat/ Somewhat complete implementation of fat_node_get().  
2831 5945 d 7 h jermar /trunk/uspace/ Commit progress on the FAT file system server implementation.  
2828 5946 d 11 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 5947 d 11 h jermar /trunk/uspace/srv/fs/fat/ Introduce and also use the foundation of block cache API in FAT's match
operation.		  
2821 5947 d 11 h jermar /trunk/uspace/srv/vfs/ Update comment.  
2798 5951 d 15 h jermar /trunk/uspace/ Replace all endian.h in uspace with a copy of the kernel's respective byteorder.h.  
2796 5952 d 15 h jermar /trunk/uspace/srv/fs/fat/ Convert FAT on-disk metadata from little-endian to native representation.  
2793 5952 d 16 h jermar /trunk/uspace/srv/fs/fat/ First untested bits of FAT lookup support.  
2792 5952 d 16 h jermar /trunk/uspace/ libfs' node_get() operation does not need the file system handle.  
2791 5955 d 13 h jermar /trunk/uspace/ Make libfs_lookup() more generic.  
2789 5958 d 3 h jermar /trunk/uspace/srv/fs/fat/ Fix FAT boot sector definition and introduce the FAT in-core node type.  
2788 5958 d 4 h jermar /trunk/uspace/ Return EBUSY if trying to mount something over an already mounted root FS.
(Contributed by Tim Post)		  
2770 5974 d 15 h jermar /trunk/uspace/ Introduce fs_handle_t, dev_handle_t and fs_index_t.  
2769 5975 d 14 h jermar /trunk/uspace/srv/vfs/ VFS index needs to be treated as uint64_t.  
2768 5975 d 16 h jermar /trunk/uspace/srv/vfs/ Fibril serialization is required when two file systems register contemporarily.  
2766 5976 d 16 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 5976 d 19 h jermar /trunk/uspace/ Support for rename().  
2760 5979 d 13 h jermar /trunk/uspace/ Support for multiple TMPFS node names.  
2758 5980 d 14 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 5980 d 15 h jermar /trunk/uspace/srv/fs/tmpfs/ Set the TMPFS root node's link count to 1.  
2756 5980 d 16 h jermar /trunk/uspace/srv/fs/tmpfs/ Introduce real link counts for TMPFS.  
2753 5983 d 14 h jermar /trunk/uspace/ Move canonify() to libc so that it can be used also on the libc side.  
2752 5983 d 21 h jermar /trunk/uspace/srv/vfs/ Make VFS canonify path names on lookup.  
2751 5984 d 19 h jermar /trunk/uspace/ Add canonify() for file system path canonization.
Not yet used by VFS.		  
2749 5986 d 14 h jermar /trunk/uspace/srv/vfs/ contents_rwlock should not be acquired as a futex but rather as a rwlock.  
2748 5986 d 14 h jermar /trunk/uspace/srv/vfs/ Support for O_TRUNC.  
2747 5987 d 13 h jermar /trunk/uspace/ Move the core lookup logic from TMPFS to libfs.  
2742 5989 d 14 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().		  
2740 5995 d 14 h jermar /trunk/uspace/srv/vfs/ Initialize the VFS node properly.
