2793 5957 d 8 h jermar /trunk/uspace/srv/fs/fat/ First untested bits of FAT lookup support.  
2792 5957 d 8 h jermar /trunk/uspace/ libfs' node_get() operation does not need the file system handle.  
2791 5960 d 5 h jermar /trunk/uspace/ Make libfs_lookup() more generic.  
2789 5962 d 19 h jermar /trunk/uspace/srv/fs/fat/ Fix FAT boot sector definition and introduce the FAT in-core node type.  
2788 5962 d 20 h jermar /trunk/uspace/ Return EBUSY if trying to mount something over an already mounted root FS.
(Contributed by Tim Post)		  
2770 5979 d 7 h jermar /trunk/uspace/ Introduce fs_handle_t, dev_handle_t and fs_index_t.  
2769 5980 d 6 h jermar /trunk/uspace/srv/vfs/ VFS index needs to be treated as uint64_t.  
2768 5980 d 8 h jermar /trunk/uspace/srv/vfs/ Fibril serialization is required when two file systems register contemporarily.  
2766 5981 d 8 h jermar /trunk/uspace/srv/vfs/ Grab the nodes_futex when manipulating node link counts in rename() and
_unlink().

Fix VFS futex definitions and declarations by replacing atomic_t by futex_t.		  
2763 5981 d 10 h jermar /trunk/uspace/ Support for rename().  
2760 5984 d 5 h jermar /trunk/uspace/ Support for multiple TMPFS node names.  
2758 5985 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 5985 d 7 h jermar /trunk/uspace/srv/fs/tmpfs/ Set the TMPFS root node's link count to 1.  
2756 5985 d 8 h jermar /trunk/uspace/srv/fs/tmpfs/ Introduce real link counts for TMPFS.  
2753 5988 d 6 h jermar /trunk/uspace/ Move canonify() to libc so that it can be used also on the libc side.  
2752 5988 d 13 h jermar /trunk/uspace/srv/vfs/ Make VFS canonify path names on lookup.  
2751 5989 d 11 h jermar /trunk/uspace/ Add canonify() for file system path canonization.
Not yet used by VFS.		  
2749 5991 d 6 h jermar /trunk/uspace/srv/vfs/ contents_rwlock should not be acquired as a futex but rather as a rwlock.  
2748 5991 d 6 h jermar /trunk/uspace/srv/vfs/ Support for O_TRUNC.  
2747 5992 d 5 h jermar /trunk/uspace/ Move the core lookup logic from TMPFS to libfs.  
2742 5994 d 5 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().		  
2740 6000 d 6 h jermar /trunk/uspace/srv/vfs/ Initialize the VFS node properly.  
2739 6000 d 6 h jermar /trunk/uspace/srv/fs/tmpfs/ Remove duplicate initialization.  
2736 6002 d 8 h jermar /trunk/uspace/srv/fs/tmpfs/ Unlink a TMPFS node more thoroughly.  
2735 6002 d 11 h jermar /trunk/uspace/ Support for rmdir(), unlink() and the respective VFS operations.  
2734 6002 d 13 h jermar /trunk/uspace/ Support for close().  
2733 6002 d 13 h jermar /trunk/uspace/ Add TMPFS support for destroying leaf links in the file system namespace.  
2732 6002 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 6002 d 14 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 6003 d 16 h jermar /trunk/uspace/srv/ Introduce the notion of VFS node link counts.  
2728 6008 d 6 h jermar /trunk/uspace/srv/fs/tmpfs/ Descend vs. descent.  
2711 6023 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 6023 d 9 h jermar /trunk/uspace/ VFS_WRITE and tmpfs_write fixes.  
2709 6023 d 11 h jermar /trunk/uspace/srv/vfs/ VFS_OPEN and VFS_WRITE now understand O_APPEND.  
2708 6023 d 11 h jermar /trunk/uspace/ VFS_OPEN now understands O_CREAT and O_EXCL.  
2707 6023 d 13 h jermar /trunk/uspace/ Support for mkdir().  
2706 6023 d 17 h jermar /trunk/uspace/srv/fs/tmpfs/ Move handling of the miss on excessive components out of the main loop in
tmpfs_lookup.		  
2705 6024 d 5 h jermar /trunk/uspace/ More elegant, flexible and complete version of tmpfs_lookup.  
2704 6024 d 16 h jermar /trunk/uspace/srv/vfs/ Additional VFS lookup flags.  
2700 6031 d 14 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).
