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

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.
 
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 9 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.  
2770 5969 d 11 h jermar /trunk/uspace/ Introduce fs_handle_t, dev_handle_t and fs_index_t.  
2763 5971 d 14 h jermar /trunk/uspace/ Support for rename().  
2760 5974 d 9 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.  
2747 5982 d 8 h jermar /trunk/uspace/ Move the core lookup logic from TMPFS to libfs.  
2742 5984 d 9 h jermar /trunk/uspace/srv/ Separate creation of a TMPFS node and its linking in the file system name space.
Rename VFS_FREE to VFS_DESTROY and destroy_node() to unlink_node().
 
2739 5990 d 9 h jermar /trunk/uspace/srv/fs/tmpfs/ Remove duplicate initialization.  
2736 5992 d 11 h jermar /trunk/uspace/srv/fs/tmpfs/ Unlink a TMPFS node more thoroughly.  
2735 5992 d 15 h jermar /trunk/uspace/ Support for rmdir(), unlink() and the respective VFS operations.  
2733 5992 d 17 h jermar /trunk/uspace/ Add TMPFS support for destroying leaf links in the file system namespace.  
2732 5992 d 17 h jermar /trunk/uspace/srv/fs/tmpfs/ When freeing up a TMPFS node, it should also be removed from the dentries hash table.  
2731 5992 d 18 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.
 
2730 5993 d 20 h jermar /trunk/uspace/srv/ Introduce the notion of VFS node link counts.  
2728 5998 d 9 h jermar /trunk/uspace/srv/fs/tmpfs/ Descend vs. descent.  
2711 6013 d 12 h jermar /trunk/uspace/ Remove the debugging hack from tmpfs_init(), which created several files and
directories on the filesystem. TMPFS is now self-sufficient enough to be able
to create its content via the standard VFS interface.
 
2710 6013 d 12 h jermar /trunk/uspace/ VFS_WRITE and tmpfs_write fixes.  
2707 6013 d 16 h jermar /trunk/uspace/ Support for mkdir().  
2706 6013 d 20 h jermar /trunk/uspace/srv/fs/tmpfs/ Move handling of the miss on excessive components out of the main loop in
tmpfs_lookup.
 
2705 6014 d 9 h jermar /trunk/uspace/ More elegant, flexible and complete version of tmpfs_lookup.  
2700 6021 d 17 h jermar /trunk/uspace/ Introduce the notion of lflag (i.e. lookup flags) to support the ability to
limit the scope of VFS node types that can be opened by open() and opendir(). In
the future, lflag will also specify actions for VFS_LOOKUP handlers that will be
carried out in situations such as the VFS node is not found (e.g. implementation
of mkdir() and open() with O_CREAT in oflag).
 
2699 6022 d 7 h jermar /trunk/uspace/ Finish implementation of readdir(). Functions from this family are implemented
via using file descriptors for directories. For example, readdir() is
implemented as read() from an open directory. Of course, FS implementations
must understand that they are asked to read a directory and behave accordingly.
 
2693 6027 d 18 h jermar /trunk/uspace/ Add ftruncate() and support for VFS_TRUNCATE to VFS and TMPFS.  
2690 6032 d 9 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.
