3503 5747 d 12 h jermar /trunk/uspace/srv/fs/fat/ Implementation of fat_alloc_clusters().  
3501 5748 d 3 h jermar /trunk/uspace/srv/fs/fat/ Implementation of fat_fill_gap().  
3500 5748 d 5 h jermar /trunk/uspace/srv/fs/fat/ More complete prototype of fat_write().  
3499 5748 d 8 h jermar /trunk/uspace/srv/fs/fat/ Mark progress in fat_write().  
3497 5748 d 12 h jermar /trunk/uspace/srv/fs/fat/ Dummy fat_write().  
3352 5812 d 3 h jermar /trunk/uspace/srv/ Add reference to the mounted FS root.

This makes it possible to keep the FS root logically unlinked (i.e. lnkcnt == 0)
because it prevents VFS from attempting to destroy it during closedir().
 
3335 5816 d 2 h jermar /trunk/uspace/srv/fs/fat/ Support for readdir() on FAT.  
3325 5819 d 3 h jermar /trunk/uspace/srv/fs/fat/ Determine the size of a directory node by walking the FAT and counting clusters.
This eliminates the hardcoded limit on the number of directory entries.
 
3314 5820 d 4 h jermar /trunk/uspace/srv/fs/fat/ fat_read() should expect IPC_M_DATA_READ instead of IPC_M_DATA_WRITE.  
3312 5820 d 4 h jermar /trunk/uspace/srv/fs/fat/ When removing a FAT node from the ffn list, use the correct pointer instead of
an uninitialized one.
 
3308 5822 d 2 h jermar /trunk/uspace/srv/fs/fat/ More complete fat_read().  
3307 5822 d 4 h jermar /trunk/uspace/srv/fs/fat/ Dummy implementation of fat_read().  
3282 5824 d 1 h jermar /trunk/uspace/srv/fs/fat/ FAT dentry type used for subdirectories doesn't store the directory size in the 'size' field.
Introduce a simple workaround that will let us have 64 directory entries at maximum.
 
3272 5824 d 14 h jermar /trunk/uspace/srv/fs/fat/ Several fixes for the FAT file system:
- do not copy padding during file name canonization
- properly nul-terminate the FAT file name during canonization
- compare FAT file name and the component name case insensitively
- block_get() takes a block offset, not byte offset as parameter
 
3257 5825 d 13 h jermar /trunk/uspace/srv/fs/fat/ First attempt at delivering the FAT16 read-only support.
Needless to say it doesn't work yet, but now it's only
the lurking bugs that need to be fixed.
 
3253 5827 d 1 h jermar /trunk/uspace/srv/fs/fat/ Pass block size to block_get() in the last argument.  
3201 5862 d 10 h svoboda /trunk/uspace/ Do not disassemble needlessly.  
3119 5888 d 8 h jermar /trunk/uspace/srv/fs/fat/ Initialize in-core FAT root directory node during mount.  
3111 5889 d 2 h jermar /trunk/uspace/srv/fs/fat/ Put a frequently used construct into a function.  
3110 5889 d 3 h jermar /trunk/uspace/srv/fs/fat/ Initialize global FAT IDX structures when the FAT server starts and initialize
per-file system FAT IDX structures when a file system gets mounted.
 
2953 5909 d 2 h jermar /trunk/uspace/srv/fs/fat/ Add synchronization to fat_match().  
2951 5909 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 5910 d 2 h jermar /trunk/uspace/srv/fs/fat/ Introduce a futex protecting the up_hash and ui_hash.  
2944 5910 d 2 h jermar /trunk/uspace/srv/fs/fat/ Introduce futex for protecting the list of unused structures in FAT server.  
2910 5914 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 5915 d 12 h jermar /trunk/uspace/srv/fs/fat/ More bits of fat_node_get().
Still needs to do some locking.
 
2891 5918 d 2 h jermar /trunk/uspace/srv/fs/fat/ New first bits of fat_node_get().  
2890 5918 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 5921 d 3 h jermar /trunk/uspace/srv/fs/fat/ Add hash table for used fat_idx_t structures and implement fat_idx_map().  
2884 5922 d 2 h jermar /trunk/uspace/srv/fs/fat/ merge vs. coalesce  
2881 5922 d 7 h jermar /trunk/uspace/srv/fs/fat/ Code for de/allocation of VFS indices for FAT.  
2876 5922 d 10 h jermar /trunk/uspace/srv/fs/fat/ Add a dedicated source file for handling FAT indices.  
2864 5936 d 0 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 5936 d 12 h jermar /trunk/uspace/ Revert libfs node_get() API to a model without the parent node pointer
argument.
 
2859 5941 d 17 h jermar /trunk/uspace/srv/fs/fat/ Add fat_block_get().  
2858 5941 d 20 h jermar /trunk/uspace/ libfs destroy operation should rather return an error code instead of a truth
value.
 
2857 5941 d 20 h jermar /trunk/uspace/ Add stubs for unimplemented FAT libfs operations.  
2856 5941 d 20 h jermar /trunk/uspace/srv/fs/fat/ Add a locking scheme for FAT in-core cache and nodes.  
2855 5941 d 21 h jermar /trunk/uspace/srv/fs/fat/ fat_node_put(). No locking so far.  
2852 5942 d 18 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.

appropriate places.
