2758 5946 d 6 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 5946 d 8 h jermar /trunk/uspace/srv/fs/tmpfs/ Set the TMPFS root node's link count to 1.  
2756 5946 d 8 h jermar /trunk/uspace/srv/fs/tmpfs/ Introduce real link counts for TMPFS.  
2747 5953 d 5 h jermar /trunk/uspace/ Move the core lookup logic from TMPFS to libfs.  
2742 5955 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 5961 d 6 h jermar /trunk/uspace/srv/fs/tmpfs/ Remove duplicate initialization.  
2736 5963 d 8 h jermar /trunk/uspace/srv/fs/tmpfs/ Unlink a TMPFS node more thoroughly.  
2735 5963 d 12 h jermar /trunk/uspace/ Support for rmdir(), unlink() and the respective VFS operations.  
2733 5963 d 14 h jermar /trunk/uspace/ Add TMPFS support for destroying leaf links in the file system namespace.  
2732 5963 d 14 h jermar /trunk/uspace/srv/fs/tmpfs/ When freeing up a TMPFS node, it should also be removed from the dentries hash table.  
2731 5963 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 5964 d 17 h jermar /trunk/uspace/srv/ Introduce the notion of VFS node link counts.  
2728 5969 d 6 h jermar /trunk/uspace/srv/fs/tmpfs/ Descend vs. descent.  
2711 5984 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 5984 d 9 h jermar /trunk/uspace/ VFS_WRITE and tmpfs_write fixes.  
2707 5984 d 13 h jermar /trunk/uspace/ Support for mkdir().  
2706 5984 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 5985 d 6 h jermar /trunk/uspace/ More elegant, flexible and complete version of tmpfs_lookup.  
2700 5992 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 5993 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.
