2770 5938 d 20 h jermar /trunk/uspace/ Introduce fs_handle_t, dev_handle_t and fs_index_t.  
2769 5939 d 19 h jermar /trunk/uspace/srv/vfs/ VFS index needs to be treated as uint64_t.  
2768 5939 d 21 h jermar /trunk/uspace/srv/vfs/ Fibril serialization is required when two file systems register contemporarily.  
2766 5940 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 5940 d 23 h jermar /trunk/uspace/ Support for rename().  
2760 5943 d 18 h jermar /trunk/uspace/ Support for multiple TMPFS node names.  
2758 5944 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 5944 d 20 h jermar /trunk/uspace/srv/fs/tmpfs/ Set the TMPFS root node's link count to 1.  
2756 5944 d 21 h jermar /trunk/uspace/srv/fs/tmpfs/ Introduce real link counts for TMPFS.  
2753 5947 d 19 h jermar /trunk/uspace/ Move canonify() to libc so that it can be used also on the libc side.  
2752 5948 d 2 h jermar /trunk/uspace/srv/vfs/ Make VFS canonify path names on lookup.  
2751 5949 d 0 h jermar /trunk/uspace/ Add canonify() for file system path canonization.
Not yet used by VFS.
 
2749 5950 d 19 h jermar /trunk/uspace/srv/vfs/ contents_rwlock should not be acquired as a futex but rather as a rwlock.  
2748 5950 d 19 h jermar /trunk/uspace/srv/vfs/ Support for O_TRUNC.  
2747 5951 d 18 h jermar /trunk/uspace/ Move the core lookup logic from TMPFS to libfs.  
2742 5953 d 18 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 5959 d 19 h jermar /trunk/uspace/srv/vfs/ Initialize the VFS node properly.  
2739 5959 d 19 h jermar /trunk/uspace/srv/fs/tmpfs/ Remove duplicate initialization.  
2736 5961 d 21 h jermar /trunk/uspace/srv/fs/tmpfs/ Unlink a TMPFS node more thoroughly.  
2735 5962 d 0 h jermar /trunk/uspace/ Support for rmdir(), unlink() and the respective VFS operations.  
2734 5962 d 2 h jermar /trunk/uspace/ Support for close().  
2733 5962 d 2 h jermar /trunk/uspace/ Add TMPFS support for destroying leaf links in the file system namespace.  
2732 5962 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 5962 d 3 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 5963 d 5 h jermar /trunk/uspace/srv/ Introduce the notion of VFS node link counts.  
2728 5967 d 19 h jermar /trunk/uspace/srv/fs/tmpfs/ Descend vs. descent.  
2711 5982 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 5982 d 22 h jermar /trunk/uspace/ VFS_WRITE and tmpfs_write fixes.  
2709 5983 d 0 h jermar /trunk/uspace/srv/vfs/ VFS_OPEN and VFS_WRITE now understand O_APPEND.  
2708 5983 d 0 h jermar /trunk/uspace/ VFS_OPEN now understands O_CREAT and O_EXCL.  
2707 5983 d 2 h jermar /trunk/uspace/ Support for mkdir().  
2706 5983 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 5983 d 18 h jermar /trunk/uspace/ More elegant, flexible and complete version of tmpfs_lookup.  
2704 5984 d 4 h jermar /trunk/uspace/srv/vfs/ Additional VFS lookup flags.  
2700 5991 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 5991 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 5991 d 23 h jermar /trunk/uspace/srv/vfs/ Small fix for VFS_TRUNCATE. Move lookup and registration code to separate
modules.
 
2693 5997 d 3 h jermar /trunk/uspace/ Add ftruncate() and support for VFS_TRUNCATE to VFS and TMPFS.  
2691 6000 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 6001 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.
