2757 5929 d 8 h jermar /trunk/uspace/srv/fs/tmpfs/ Set the TMPFS root node's link count to 1.  
2756 5929 d 9 h jermar /trunk/uspace/srv/fs/tmpfs/ Introduce real link counts for TMPFS.  
2747 5936 d 6 h jermar /trunk/uspace/ Move the core lookup logic from TMPFS to libfs.  
2742 5938 d 6 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 5944 d 7 h jermar /trunk/uspace/srv/fs/tmpfs/ Remove duplicate initialization.  
2736 5946 d 9 h jermar /trunk/uspace/srv/fs/tmpfs/ Unlink a TMPFS node more thoroughly.  
2735 5946 d 12 h jermar /trunk/uspace/ Support for rmdir(), unlink() and the respective VFS operations.  
2733 5946 d 14 h jermar /trunk/uspace/ Add TMPFS support for destroying leaf links in the file system namespace.  
2732 5946 d 15 h jermar /trunk/uspace/srv/fs/tmpfs/ When freeing up a TMPFS node, it should also be removed from the dentries hash table.  
2731 5946 d 15 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 5947 d 17 h jermar /trunk/uspace/srv/ Introduce the notion of VFS node link counts.  
2728 5952 d 7 h jermar /trunk/uspace/srv/fs/tmpfs/ Descend vs. descent.  
2711 5967 d 9 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 5967 d 10 h jermar /trunk/uspace/ VFS_WRITE and tmpfs_write fixes.  
2707 5967 d 14 h jermar /trunk/uspace/ Support for mkdir().  
2706 5967 d 18 h jermar /trunk/uspace/srv/fs/tmpfs/ Move handling of the miss on excessive components out of the main loop in
tmpfs_lookup.		  
2705 5968 d 6 h jermar /trunk/uspace/ More elegant, flexible and complete version of tmpfs_lookup.  
2700 5975 d 15 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 5976 d 5 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 5981 d 15 h jermar /trunk/uspace/ Add ftruncate() and support for VFS_TRUNCATE to VFS and TMPFS.
