2821 5963 d 1 h jermar /trunk/uspace/srv/vfs/ Update comment.  
2798 5967 d 6 h jermar /trunk/uspace/ Replace all endian.h in uspace with a copy of the kernel's respective byteorder.h.  
2796 5968 d 6 h jermar /trunk/uspace/srv/fs/fat/ Convert FAT on-disk metadata from little-endian to native representation.  
2793 5968 d 7 h jermar /trunk/uspace/srv/fs/fat/ First untested bits of FAT lookup support.  
2792 5968 d 7 h jermar /trunk/uspace/ libfs' node_get() operation does not need the file system handle.  
2791 5971 d 4 h jermar /trunk/uspace/ Make libfs_lookup() more generic.  
2789 5973 d 18 h jermar /trunk/uspace/srv/fs/fat/ Fix FAT boot sector definition and introduce the FAT in-core node type.  
2788 5973 d 19 h jermar /trunk/uspace/ Return EBUSY if trying to mount something over an already mounted root FS.
(Contributed by Tim Post)		  
2770 5990 d 6 h jermar /trunk/uspace/ Introduce fs_handle_t, dev_handle_t and fs_index_t.  
2769 5991 d 4 h jermar /trunk/uspace/srv/vfs/ VFS index needs to be treated as uint64_t.  
2768 5991 d 6 h jermar /trunk/uspace/srv/vfs/ Fibril serialization is required when two file systems register contemporarily.  
2766 5992 d 6 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 5992 d 9 h jermar /trunk/uspace/ Support for rename().  
2760 5995 d 4 h jermar /trunk/uspace/ Support for multiple TMPFS node names.  
2758 5996 d 4 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 5996 d 6 h jermar /trunk/uspace/srv/fs/tmpfs/ Set the TMPFS root node's link count to 1.  
2756 5996 d 7 h jermar /trunk/uspace/srv/fs/tmpfs/ Introduce real link counts for TMPFS.  
2753 5999 d 5 h jermar /trunk/uspace/ Move canonify() to libc so that it can be used also on the libc side.  
2752 5999 d 11 h jermar /trunk/uspace/srv/vfs/ Make VFS canonify path names on lookup.  
2751 6000 d 9 h jermar /trunk/uspace/ Add canonify() for file system path canonization.
Not yet used by VFS.		  
2749 6002 d 5 h jermar /trunk/uspace/srv/vfs/ contents_rwlock should not be acquired as a futex but rather as a rwlock.  
2748 6002 d 5 h jermar /trunk/uspace/srv/vfs/ Support for O_TRUNC.  
2747 6003 d 4 h jermar /trunk/uspace/ Move the core lookup logic from TMPFS to libfs.  
2742 6005 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 6011 d 4 h jermar /trunk/uspace/srv/vfs/ Initialize the VFS node properly.  
2739 6011 d 4 h jermar /trunk/uspace/srv/fs/tmpfs/ Remove duplicate initialization.  
2736 6013 d 6 h jermar /trunk/uspace/srv/fs/tmpfs/ Unlink a TMPFS node more thoroughly.  
2735 6013 d 10 h jermar /trunk/uspace/ Support for rmdir(), unlink() and the respective VFS operations.  
2734 6013 d 12 h jermar /trunk/uspace/ Support for close().  
2733 6013 d 12 h jermar /trunk/uspace/ Add TMPFS support for destroying leaf links in the file system namespace.  
2732 6013 d 12 h jermar /trunk/uspace/srv/fs/tmpfs/ When freeing up a TMPFS node, it should also be removed from the dentries hash table.  
2731 6013 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 6014 d 15 h jermar /trunk/uspace/srv/ Introduce the notion of VFS node link counts.  
2728 6019 d 4 h jermar /trunk/uspace/srv/fs/tmpfs/ Descend vs. descent.  
2711 6034 d 7 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 6034 d 8 h jermar /trunk/uspace/ VFS_WRITE and tmpfs_write fixes.  
2709 6034 d 10 h jermar /trunk/uspace/srv/vfs/ VFS_OPEN and VFS_WRITE now understand O_APPEND.  
2708 6034 d 10 h jermar /trunk/uspace/ VFS_OPEN now understands O_CREAT and O_EXCL.  
2707 6034 d 11 h jermar /trunk/uspace/ Support for mkdir().  
2706 6034 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.
