2884 5915 d 10 h jermar /trunk/uspace/srv/fs/fat/ merge vs. coalesce  
2881 5915 d 15 h jermar /trunk/uspace/srv/fs/fat/ Code for de/allocation of VFS indices for FAT.  
2876 5915 d 18 h jermar /trunk/uspace/srv/fs/fat/ Add a dedicated source file for handling FAT indices.  
2864 5929 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 5929 d 20 h jermar /trunk/uspace/ Revert libfs node_get() API to a model without the parent node pointer
argument.		  
2859 5935 d 1 h jermar /trunk/uspace/srv/fs/fat/ Add fat_block_get().  
2858 5935 d 4 h jermar /trunk/uspace/ libfs destroy operation should rather return an error code instead of a truth
value.		  
2857 5935 d 4 h jermar /trunk/uspace/ Add stubs for unimplemented FAT libfs operations.  
2856 5935 d 4 h jermar /trunk/uspace/srv/fs/fat/ Add a locking scheme for FAT in-core cache and nodes.  
2855 5935 d 5 h jermar /trunk/uspace/srv/fs/fat/ fat_node_put(). No locking so far.  
2852 5936 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 5937 d 8 h jermar /trunk/uspace/srv/fs/fat/ Add fat_has_children(). Alse assume that fat_block_get() can never return NULL.  
2844 5937 d 8 h jermar /trunk/uspace/ Add fat_root_get() and fat_plb_get_char().  
2843 5937 d 9 h jermar /trunk/uspace/srv/fs/fat/ Somewhat complete implementation of fat_node_get().  
2831 5940 d 2 h jermar /trunk/uspace/ Commit progress on the FAT file system server implementation.  
2828 5941 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 5942 d 6 h jermar /trunk/uspace/srv/fs/fat/ Introduce and also use the foundation of block cache API in FAT's match
operation.		  
2821 5942 d 6 h jermar /trunk/uspace/srv/vfs/ Update comment.  
2798 5946 d 10 h jermar /trunk/uspace/ Replace all endian.h in uspace with a copy of the kernel's respective byteorder.h.  
2796 5947 d 10 h jermar /trunk/uspace/srv/fs/fat/ Convert FAT on-disk metadata from little-endian to native representation.  
2793 5947 d 11 h jermar /trunk/uspace/srv/fs/fat/ First untested bits of FAT lookup support.  
2792 5947 d 11 h jermar /trunk/uspace/ libfs' node_get() operation does not need the file system handle.  
2791 5950 d 8 h jermar /trunk/uspace/ Make libfs_lookup() more generic.  
2789 5952 d 22 h jermar /trunk/uspace/srv/fs/fat/ Fix FAT boot sector definition and introduce the FAT in-core node type.  
2788 5952 d 23 h jermar /trunk/uspace/ Return EBUSY if trying to mount something over an already mounted root FS.
(Contributed by Tim Post)		  
2770 5969 d 10 h jermar /trunk/uspace/ Introduce fs_handle_t, dev_handle_t and fs_index_t.  
2769 5970 d 9 h jermar /trunk/uspace/srv/vfs/ VFS index needs to be treated as uint64_t.  
2768 5970 d 11 h jermar /trunk/uspace/srv/vfs/ Fibril serialization is required when two file systems register contemporarily.  
2766 5971 d 11 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 5971 d 14 h jermar /trunk/uspace/ Support for rename().  
2760 5974 d 8 h jermar /trunk/uspace/ Support for multiple TMPFS node names.  
2758 5975 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 5975 d 10 h jermar /trunk/uspace/srv/fs/tmpfs/ Set the TMPFS root node's link count to 1.  
2756 5975 d 11 h jermar /trunk/uspace/srv/fs/tmpfs/ Introduce real link counts for TMPFS.  
2753 5978 d 10 h jermar /trunk/uspace/ Move canonify() to libc so that it can be used also on the libc side.  
2752 5978 d 16 h jermar /trunk/uspace/srv/vfs/ Make VFS canonify path names on lookup.  
2751 5979 d 14 h jermar /trunk/uspace/ Add canonify() for file system path canonization.
Not yet used by VFS.		  
2749 5981 d 9 h jermar /trunk/uspace/srv/vfs/ contents_rwlock should not be acquired as a futex but rather as a rwlock.  
2748 5981 d 9 h jermar /trunk/uspace/srv/vfs/ Support for O_TRUNC.  
2747 5982 d 8 h jermar /trunk/uspace/ Move the core lookup logic from TMPFS to libfs.
