2791 5963 d 4 h jermar /trunk/uspace/ Make libfs_lookup() more generic.  
2789 5965 d 18 h jermar /trunk/uspace/srv/fs/fat/ Fix FAT boot sector definition and introduce the FAT in-core node type.  
2788 5965 d 19 h jermar /trunk/uspace/ Return EBUSY if trying to mount something over an already mounted root FS.
(Contributed by Tim Post)
 
2770 5982 d 6 h jermar /trunk/uspace/ Introduce fs_handle_t, dev_handle_t and fs_index_t.  
2769 5983 d 5 h jermar /trunk/uspace/srv/vfs/ VFS index needs to be treated as uint64_t.  
2768 5983 d 7 h jermar /trunk/uspace/srv/vfs/ Fibril serialization is required when two file systems register contemporarily.  
2766 5984 d 7 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 5984 d 9 h jermar /trunk/uspace/ Support for rename().  
2760 5987 d 4 h jermar /trunk/uspace/ Support for multiple TMPFS node names.  
2758 5988 d 5 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 5988 d 6 h jermar /trunk/uspace/srv/fs/tmpfs/ Set the TMPFS root node's link count to 1.  
2756 5988 d 7 h jermar /trunk/uspace/srv/fs/tmpfs/ Introduce real link counts for TMPFS.  
2753 5991 d 5 h jermar /trunk/uspace/ Move canonify() to libc so that it can be used also on the libc side.  
2752 5991 d 12 h jermar /trunk/uspace/srv/vfs/ Make VFS canonify path names on lookup.  
2751 5992 d 10 h jermar /trunk/uspace/ Add canonify() for file system path canonization.
Not yet used by VFS.
 
2749 5994 d 5 h jermar /trunk/uspace/srv/vfs/ contents_rwlock should not be acquired as a futex but rather as a rwlock.  
2748 5994 d 5 h jermar /trunk/uspace/srv/vfs/ Support for O_TRUNC.  
2747 5995 d 4 h jermar /trunk/uspace/ Move the core lookup logic from TMPFS to libfs.  
2742 5997 d 4 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 6003 d 5 h jermar /trunk/uspace/srv/vfs/ Initialize the VFS node properly.  
2739 6003 d 5 h jermar /trunk/uspace/srv/fs/tmpfs/ Remove duplicate initialization.  
2736 6005 d 7 h jermar /trunk/uspace/srv/fs/tmpfs/ Unlink a TMPFS node more thoroughly.  
2735 6005 d 10 h jermar /trunk/uspace/ Support for rmdir(), unlink() and the respective VFS operations.  
2734 6005 d 12 h jermar /trunk/uspace/ Support for close().  
2733 6005 d 12 h jermar /trunk/uspace/ Add TMPFS support for destroying leaf links in the file system namespace.  
2732 6005 d 13 h jermar /trunk/uspace/srv/fs/tmpfs/ When freeing up a TMPFS node, it should also be removed from the dentries hash table.  
2731 6005 d 13 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 6006 d 15 h jermar /trunk/uspace/srv/ Introduce the notion of VFS node link counts.  
2728 6011 d 5 h jermar /trunk/uspace/srv/fs/tmpfs/ Descend vs. descent.  
2711 6026 d 8 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 6026 d 8 h jermar /trunk/uspace/ VFS_WRITE and tmpfs_write fixes.  
2709 6026 d 10 h jermar /trunk/uspace/srv/vfs/ VFS_OPEN and VFS_WRITE now understand O_APPEND.  
2708 6026 d 10 h jermar /trunk/uspace/ VFS_OPEN now understands O_CREAT and O_EXCL.  
2707 6026 d 12 h jermar /trunk/uspace/ Support for mkdir().  
2706 6026 d 16 h jermar /trunk/uspace/srv/fs/tmpfs/ Move handling of the miss on excessive components out of the main loop in
tmpfs_lookup.
 
2705 6027 d 4 h jermar /trunk/uspace/ More elegant, flexible and complete version of tmpfs_lookup.  
2704 6027 d 15 h jermar /trunk/uspace/srv/vfs/ Additional VFS lookup flags.  
2700 6034 d 13 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 6035 d 3 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.
 
2698 6035 d 9 h jermar /trunk/uspace/srv/vfs/ Small fix for VFS_TRUNCATE. Move lookup and registration code to separate
modules.
