3007 5843 d 4 h jermar /trunk/ Improve linking and loading of boot ELF images.
(Contributed by Jiri Svoboda)		  
3003 5844 d 4 h jermar /trunk/uspace/lib/libfs/ More of the preivous commit.  
3002 5844 d 4 h jermar /trunk/uspace/lib/libfs/ Optimize conditions in libfs_lookup(). Perform primitive comparisons in the
left-hand subexpression and potentially expensive calls to libfs operations in
the right-hand subexpression.		  
2958 5851 d 1 h jermar /trunk/uspace/srv/ Make VFS_MOUNT call even when mounting the root file system.  
2957 5851 d 3 h jermar /trunk/uspace/srv/vfs/ Cram VFS_MOUNT into one message. This creates a hidden demand for the sixth IPC
argument as there might be a desire to pass some options/flags in the future.		  
2953 5852 d 2 h jermar /trunk/uspace/srv/fs/fat/ Add synchronization to fat_match().  
2951 5852 d 3 h jermar /trunk/uspace/srv/fs/fat/ Add locks to FAT index structures, FAT in-core node structures. Add futex to
protect the list of free cached FAT in-core nodes. Make fat_node_get() and
fat_node_put() and some other functions aware of these new locks.		  
2945 5853 d 2 h jermar /trunk/uspace/srv/fs/fat/ Introduce a futex protecting the up_hash and ui_hash.  
2944 5853 d 2 h jermar /trunk/uspace/srv/fs/fat/ Introduce futex for protecting the list of unused structures in FAT server.  
2934 5854 d 5 h jermar /trunk/ Do not attempt to malloc() zero bytes of memory during VFS_READ at end of file.  
2910 5857 d 7 h jermar /trunk/uspace/srv/fs/fat/ Implement fat_node_put() and remove the node from the free node list when
bumping its refernce count from zero in fat_node_get().		  
2893 5858 d 12 h jermar /trunk/uspace/srv/fs/fat/ More bits of fat_node_get().
Still needs to do some locking.		  
2891 5861 d 2 h jermar /trunk/uspace/srv/fs/fat/ New first bits of fat_node_get().  
2890 5861 d 4 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 5864 d 3 h jermar /trunk/uspace/srv/fs/fat/ Add hash table for used fat_idx_t structures and implement fat_idx_map().  
2884 5865 d 3 h jermar /trunk/uspace/srv/fs/fat/ merge vs. coalesce  
2881 5865 d 7 h jermar /trunk/uspace/srv/fs/fat/ Code for de/allocation of VFS indices for FAT.  
2879 5865 d 8 h jermar /trunk/uspace/lib/libc/include/libadt/ Add functions for inserting items before or after other items in a boubly-linked
circular lists.		  
2876 5865 d 11 h jermar /trunk/uspace/srv/fs/fat/ Add a dedicated source file for handling FAT indices.  
2864 5879 d 1 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.
