2951 5883 d 12 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 5884 d 11 h jermar /trunk/uspace/srv/fs/fat/ Introduce a futex protecting the up_hash and ui_hash.  
2944 5884 d 11 h jermar /trunk/uspace/srv/fs/fat/ Introduce futex for protecting the list of unused structures in FAT server.  
2910 5888 d 16 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 21 h jermar /trunk/uspace/srv/fs/fat/ More bits of fat_node_get().
Still needs to do some locking.		  
2891 5892 d 11 h jermar /trunk/uspace/srv/fs/fat/ New first bits of fat_node_get().  
2890 5892 d 13 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 5895 d 12 h jermar /trunk/uspace/srv/fs/fat/ Add hash table for used fat_idx_t structures and implement fat_idx_map().  
2884 5896 d 12 h jermar /trunk/uspace/srv/fs/fat/ merge vs. coalesce  
2881 5896 d 16 h jermar /trunk/uspace/srv/fs/fat/ Code for de/allocation of VFS indices for FAT.  
2876 5896 d 20 h jermar /trunk/uspace/srv/fs/fat/ Add a dedicated source file for handling FAT indices.  
2864 5910 d 10 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 21 h jermar /trunk/uspace/ Revert libfs node_get() API to a model without the parent node pointer
argument.		  
2859 5916 d 2 h jermar /trunk/uspace/srv/fs/fat/ Add fat_block_get().  
2858 5916 d 5 h jermar /trunk/uspace/ libfs destroy operation should rather return an error code instead of a truth
value.		  
2857 5916 d 5 h jermar /trunk/uspace/ Add stubs for unimplemented FAT libfs operations.  
2856 5916 d 6 h jermar /trunk/uspace/srv/fs/fat/ Add a locking scheme for FAT in-core cache and nodes.  
2855 5916 d 7 h jermar /trunk/uspace/srv/fs/fat/ fat_node_put(). No locking so far.  
2852 5917 d 3 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 5918 d 9 h jermar /trunk/uspace/srv/fs/fat/ Add fat_has_children(). Alse assume that fat_block_get() can never return NULL.  
2844 5918 d 10 h jermar /trunk/uspace/ Add fat_root_get() and fat_plb_get_char().  
2843 5918 d 11 h jermar /trunk/uspace/srv/fs/fat/ Somewhat complete implementation of fat_node_get().  
2831 5921 d 3 h jermar /trunk/uspace/ Commit progress on the FAT file system server implementation.  
2828 5922 d 8 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 5923 d 7 h jermar /trunk/uspace/srv/fs/fat/ Introduce and also use the foundation of block cache API in FAT's match
operation.		  
2798 5927 d 12 h jermar /trunk/uspace/ Replace all endian.h in uspace with a copy of the kernel's respective byteorder.h.  
2796 5928 d 12 h jermar /trunk/uspace/srv/fs/fat/ Convert FAT on-disk metadata from little-endian to native representation.  
2793 5928 d 13 h jermar /trunk/uspace/srv/fs/fat/ First untested bits of FAT lookup support.  
2789 5934 d 0 h jermar /trunk/uspace/srv/fs/fat/ Fix FAT boot sector definition and introduce the FAT in-core node type.  
2731 5973 d 19 h jermar /trunk/uspace/srv/ Add the VFS_FREE operation. This operation frees up whatever resources used by
a file system node for which there is no name (i.e. an unlinked node).

Cleanup VFS operations enums and remove unneeded VFS operations.		  
2690 6013 d 11 h jermar /trunk/uspace/srv/ Make a distinction between VFS operations that are common to VFS and FS
implementations, operations that are VFS only and operations that are FS
implementations only.		  
2644 6036 d 15 h jermar /trunk/uspace/ Move incomplete fs interface from fat.h to libfs.  
2643 6036 d 16 h jermar /trunk/uspace/ VFS work.
Move FS registration code to libfs.		  
2639 6047 d 10 h jermar /trunk/uspace/srv/fs/fat/ FAT work.
Foundation for FAT dentry comparison function.
Beware of looking at the diff or risk loosing sanity.		  
2638 6048 d 12 h jermar /trunk/ Sync IPC comments with IPC code.  
2637 6048 d 13 h cejka /trunk/ Extended IPC_M_CONNECT_TO_ME to use 3 user defined parameters.
Phone identifier is passed in ARG5.		  
2635 6050 d 13 h cejka /trunk/ Function ipc_connect_me_to sends 3 user defined arguments now.
One argument added also to ipc_forward_fast.
Fixed devmap and improved its test.		  
2629 6057 d 11 h jermar /trunk/uspace/srv/fs/fat/ FAT work.
Add type describing FAT directory entry.		  
2628 6057 d 12 h jermar /trunk/uspace/srv/fs/fat/ FAT work.
Add type describing FAT boot sector.		  
2627 6057 d 13 h jermar /trunk/uspace/srv/fs/fat/ FAT work.
Start VFS_LOOKUP support in FAT.
