2957 5881 d 21 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 5882 d 21 h jermar /trunk/uspace/srv/fs/fat/ Add synchronization to fat_match().  
2951 5882 d 22 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 5883 d 20 h jermar /trunk/uspace/srv/fs/fat/ Introduce a futex protecting the up_hash and ui_hash.  
2944 5883 d 21 h jermar /trunk/uspace/srv/fs/fat/ Introduce futex for protecting the list of unused structures in FAT server.  
2910 5888 d 2 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 5889 d 7 h jermar /trunk/uspace/srv/fs/fat/ More bits of fat_node_get().
Still needs to do some locking.		  
2891 5891 d 20 h jermar /trunk/uspace/srv/fs/fat/ New first bits of fat_node_get().  
2890 5891 d 22 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 5894 d 22 h jermar /trunk/uspace/srv/fs/fat/ Add hash table for used fat_idx_t structures and implement fat_idx_map().  
2884 5895 d 21 h jermar /trunk/uspace/srv/fs/fat/ merge vs. coalesce  
2881 5896 d 2 h jermar /trunk/uspace/srv/fs/fat/ Code for de/allocation of VFS indices for FAT.  
2876 5896 d 5 h jermar /trunk/uspace/srv/fs/fat/ Add a dedicated source file for handling FAT indices.  
2864 5909 d 19 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 5910 d 6 h jermar /trunk/uspace/ Revert libfs node_get() API to a model without the parent node pointer
argument.		  
2859 5915 d 12 h jermar /trunk/uspace/srv/fs/fat/ Add fat_block_get().  
2858 5915 d 15 h jermar /trunk/uspace/ libfs destroy operation should rather return an error code instead of a truth
value.		  
2857 5915 d 15 h jermar /trunk/uspace/ Add stubs for unimplemented FAT libfs operations.  
2856 5915 d 15 h jermar /trunk/uspace/srv/fs/fat/ Add a locking scheme for FAT in-core cache and nodes.  
2855 5915 d 16 h jermar /trunk/uspace/srv/fs/fat/ fat_node_put(). No locking so far.  
2852 5916 d 13 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 5917 d 19 h jermar /trunk/uspace/srv/fs/fat/ Add fat_has_children(). Alse assume that fat_block_get() can never return NULL.  
2844 5917 d 19 h jermar /trunk/uspace/ Add fat_root_get() and fat_plb_get_char().  
2843 5917 d 20 h jermar /trunk/uspace/srv/fs/fat/ Somewhat complete implementation of fat_node_get().  
2831 5920 d 13 h jermar /trunk/uspace/ Commit progress on the FAT file system server implementation.  
2828 5921 d 17 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 5922 d 16 h jermar /trunk/uspace/srv/fs/fat/ Introduce and also use the foundation of block cache API in FAT's match
operation.		  
2821 5922 d 17 h jermar /trunk/uspace/srv/vfs/ Update comment.  
2798 5926 d 21 h jermar /trunk/uspace/ Replace all endian.h in uspace with a copy of the kernel's respective byteorder.h.  
2796 5927 d 21 h jermar /trunk/uspace/srv/fs/fat/ Convert FAT on-disk metadata from little-endian to native representation.  
2793 5927 d 22 h jermar /trunk/uspace/srv/fs/fat/ First untested bits of FAT lookup support.  
2792 5927 d 22 h jermar /trunk/uspace/ libfs' node_get() operation does not need the file system handle.  
2791 5930 d 19 h jermar /trunk/uspace/ Make libfs_lookup() more generic.  
2789 5933 d 9 h jermar /trunk/uspace/srv/fs/fat/ Fix FAT boot sector definition and introduce the FAT in-core node type.  
2788 5933 d 10 h jermar /trunk/uspace/ Return EBUSY if trying to mount something over an already mounted root FS.

2770 5949 d 21 h jermar /trunk/uspace/ Introduce fs_handle_t, dev_handle_t and fs_index_t.  
2769 5950 d 20 h jermar /trunk/uspace/srv/vfs/ VFS index needs to be treated as uint64_t.  
2768 5950 d 22 h jermar /trunk/uspace/srv/vfs/ Fibril serialization is required when two file systems register contemporarily.  
2766 5951 d 22 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 5952 d 1 h jermar /trunk/uspace/ Support for rename().
