2821 5956 d 14 h jermar /trunk/uspace/srv/vfs/ Update comment.  
2798 5960 d 19 h jermar /trunk/uspace/ Replace all endian.h in uspace with a copy of the kernel's respective byteorder.h.  
2796 5961 d 19 h jermar /trunk/uspace/srv/fs/fat/ Convert FAT on-disk metadata from little-endian to native representation.  
2793 5961 d 20 h jermar /trunk/uspace/srv/fs/fat/ First untested bits of FAT lookup support.  
2792 5961 d 20 h jermar /trunk/uspace/ libfs' node_get() operation does not need the file system handle.  
2791 5964 d 17 h jermar /trunk/uspace/ Make libfs_lookup() more generic.  
2789 5967 d 7 h jermar /trunk/uspace/srv/fs/fat/ Fix FAT boot sector definition and introduce the FAT in-core node type.  
2788 5967 d 8 h jermar /trunk/uspace/ Return EBUSY if trying to mount something over an already mounted root FS.
(Contributed by Tim Post)		  
2770 5983 d 19 h jermar /trunk/uspace/ Introduce fs_handle_t, dev_handle_t and fs_index_t.  
2769 5984 d 18 h jermar /trunk/uspace/srv/vfs/ VFS index needs to be treated as uint64_t.  
2768 5984 d 20 h jermar /trunk/uspace/srv/vfs/ Fibril serialization is required when two file systems register contemporarily.  
2766 5985 d 20 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 5985 d 22 h jermar /trunk/uspace/ Support for rename().  
2760 5988 d 17 h jermar /trunk/uspace/ Support for multiple TMPFS node names.  
2758 5989 d 18 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 5989 d 19 h jermar /trunk/uspace/srv/fs/tmpfs/ Set the TMPFS root node's link count to 1.  
2756 5989 d 20 h jermar /trunk/uspace/srv/fs/tmpfs/ Introduce real link counts for TMPFS.  
2753 5992 d 18 h jermar /trunk/uspace/ Move canonify() to libc so that it can be used also on the libc side.  
2752 5993 d 1 h jermar /trunk/uspace/srv/vfs/ Make VFS canonify path names on lookup.  
2751 5993 d 23 h jermar /trunk/uspace/ Add canonify() for file system path canonization.
Not yet used by VFS.		  
2749 5995 d 18 h jermar /trunk/uspace/srv/vfs/ contents_rwlock should not be acquired as a futex but rather as a rwlock.  
2748 5995 d 18 h jermar /trunk/uspace/srv/vfs/ Support for O_TRUNC.  
2747 5996 d 17 h jermar /trunk/uspace/ Move the core lookup logic from TMPFS to libfs.  
2742 5998 d 17 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 6004 d 18 h jermar /trunk/uspace/srv/vfs/ Initialize the VFS node properly.  
2739 6004 d 18 h jermar /trunk/uspace/srv/fs/tmpfs/ Remove duplicate initialization.  
2736 6006 d 20 h jermar /trunk/uspace/srv/fs/tmpfs/ Unlink a TMPFS node more thoroughly.  
2735 6006 d 23 h jermar /trunk/uspace/ Support for rmdir(), unlink() and the respective VFS operations.  
2734 6007 d 1 h jermar /trunk/uspace/ Support for close().  
2733 6007 d 1 h jermar /trunk/uspace/ Add TMPFS support for destroying leaf links in the file system namespace.  
2732 6007 d 2 h jermar /trunk/uspace/srv/fs/tmpfs/ When freeing up a TMPFS node, it should also be removed from the dentries hash table.  
2731 6007 d 2 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 6008 d 4 h jermar /trunk/uspace/srv/ Introduce the notion of VFS node link counts.  
2728 6012 d 18 h jermar /trunk/uspace/srv/fs/tmpfs/ Descend vs. descent.  
2711 6027 d 21 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 6027 d 21 h jermar /trunk/uspace/ VFS_WRITE and tmpfs_write fixes.  
2709 6027 d 23 h jermar /trunk/uspace/srv/vfs/ VFS_OPEN and VFS_WRITE now understand O_APPEND.  
2708 6027 d 23 h jermar /trunk/uspace/ VFS_OPEN now understands O_CREAT and O_EXCL.  
2707 6028 d 1 h jermar /trunk/uspace/ Support for mkdir().  
2706 6028 d 5 h jermar /trunk/uspace/srv/fs/tmpfs/ Move handling of the miss on excessive components out of the main loop in
tmpfs_lookup.
