2770 6039 d 20 h jermar /trunk/uspace/ Introduce fs_handle_t, dev_handle_t and fs_index_t.  
2769 6040 d 19 h jermar /trunk/uspace/srv/vfs/ VFS index needs to be treated as uint64_t.  
2768 6040 d 21 h jermar /trunk/uspace/srv/vfs/ Fibril serialization is required when two file systems register contemporarily.  
2766 6041 d 21 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 6042 d 0 h jermar /trunk/uspace/ Support for rename().  
2760 6044 d 18 h jermar /trunk/uspace/ Support for multiple TMPFS node names.  
2758 6045 d 19 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 6045 d 20 h jermar /trunk/uspace/srv/fs/tmpfs/ Set the TMPFS root node's link count to 1.  
2756 6045 d 21 h jermar /trunk/uspace/srv/fs/tmpfs/ Introduce real link counts for TMPFS.  
2753 6048 d 20 h jermar /trunk/uspace/ Move canonify() to libc so that it can be used also on the libc side.  
2752 6049 d 2 h jermar /trunk/uspace/srv/vfs/ Make VFS canonify path names on lookup.  
2751 6050 d 0 h jermar /trunk/uspace/ Add canonify() for file system path canonization.
Not yet used by VFS.
 
2749 6051 d 19 h jermar /trunk/uspace/srv/vfs/ contents_rwlock should not be acquired as a futex but rather as a rwlock.  
2748 6051 d 20 h jermar /trunk/uspace/srv/vfs/ Support for O_TRUNC.  
2747 6052 d 18 h jermar /trunk/uspace/ Move the core lookup logic from TMPFS to libfs.  
2742 6054 d 19 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 6060 d 19 h jermar /trunk/uspace/srv/vfs/ Initialize the VFS node properly.  
2739 6060 d 19 h jermar /trunk/uspace/srv/fs/tmpfs/ Remove duplicate initialization.  
2736 6062 d 21 h jermar /trunk/uspace/srv/fs/tmpfs/ Unlink a TMPFS node more thoroughly.  
2735 6063 d 1 h jermar /trunk/uspace/ Support for rmdir(), unlink() and the respective VFS operations.  
2734 6063 d 2 h jermar /trunk/uspace/ Support for close().  
2733 6063 d 3 h jermar /trunk/uspace/ Add TMPFS support for destroying leaf links in the file system namespace.  
2732 6063 d 3 h jermar /trunk/uspace/srv/fs/tmpfs/ When freeing up a TMPFS node, it should also be removed from the dentries hash table.  
2731 6063 d 4 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 6064 d 6 h jermar /trunk/uspace/srv/ Introduce the notion of VFS node link counts.  
2728 6068 d 19 h jermar /trunk/uspace/srv/fs/tmpfs/ Descend vs. descent.  
2711 6083 d 22 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 6083 d 22 h jermar /trunk/uspace/ VFS_WRITE and tmpfs_write fixes.  
2709 6084 d 0 h jermar /trunk/uspace/srv/vfs/ VFS_OPEN and VFS_WRITE now understand O_APPEND.  
2708 6084 d 1 h jermar /trunk/uspace/ VFS_OPEN now understands O_CREAT and O_EXCL.  
2707 6084 d 2 h jermar /trunk/uspace/ Support for mkdir().  
2706 6084 d 6 h jermar /trunk/uspace/srv/fs/tmpfs/ Move handling of the miss on excessive components out of the main loop in
tmpfs_lookup.
 
2705 6084 d 19 h jermar /trunk/uspace/ More elegant, flexible and complete version of tmpfs_lookup.  
2704 6085 d 5 h jermar /trunk/uspace/srv/vfs/ Additional VFS lookup flags.  
2700 6092 d 3 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 6092 d 17 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 6092 d 23 h jermar /trunk/uspace/srv/vfs/ Small fix for VFS_TRUNCATE. Move lookup and registration code to separate
modules.
 
2693 6098 d 4 h jermar /trunk/uspace/ Add ftruncate() and support for VFS_TRUNCATE to VFS and TMPFS.  
2691 6101 d 21 h jermar /trunk/uspace/srv/vfs/ Improve the API for converting (VFS triplets, size) to VFS nodes by introducing
a new type for results of vfs_lookup_internal().
 
2690 6102 d 19 h jermar /trunk/uspace/srv/ Make a distinction between VFS operations that are common to VFS and FS
implementations, operations that are VFS only and operations that are FS
implementations only.
