2760 6092 d 21 h jermar /trunk/uspace/ Support for multiple TMPFS node names.  
2758 6093 d 21 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 6093 d 23 h jermar /trunk/uspace/srv/fs/tmpfs/ Set the TMPFS root node's link count to 1.  
2756 6093 d 23 h jermar /trunk/uspace/srv/fs/tmpfs/ Introduce real link counts for TMPFS.  
2747 6100 d 20 h jermar /trunk/uspace/ Move the core lookup logic from TMPFS to libfs.  
2742 6102 d 21 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 6108 d 21 h jermar /trunk/uspace/srv/fs/tmpfs/ Remove duplicate initialization.  
2736 6110 d 23 h jermar /trunk/uspace/srv/fs/tmpfs/ Unlink a TMPFS node more thoroughly.  
2735 6111 d 3 h jermar /trunk/uspace/ Support for rmdir(), unlink() and the respective VFS operations.  
2733 6111 d 5 h jermar /trunk/uspace/ Add TMPFS support for destroying leaf links in the file system namespace.  
2732 6111 d 5 h jermar /trunk/uspace/srv/fs/tmpfs/ When freeing up a TMPFS node, it should also be removed from the dentries hash table.  
2731 6111 d 6 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 6112 d 8 h jermar /trunk/uspace/srv/ Introduce the notion of VFS node link counts.  
2728 6116 d 21 h jermar /trunk/uspace/srv/fs/tmpfs/ Descend vs. descent.  
2711 6132 d 0 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 6132 d 0 h jermar /trunk/uspace/ VFS_WRITE and tmpfs_write fixes.  
2707 6132 d 4 h jermar /trunk/uspace/ Support for mkdir().  
2706 6132 d 8 h jermar /trunk/uspace/srv/fs/tmpfs/ Move handling of the miss on excessive components out of the main loop in
tmpfs_lookup.		  
2705 6132 d 21 h jermar /trunk/uspace/ More elegant, flexible and complete version of tmpfs_lookup.  
2700 6140 d 6 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).
