2760 5927 d 6 h jermar /trunk/uspace/ Support for multiple TMPFS node names.  
2758 5928 d 7 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 5928 d 8 h jermar /trunk/uspace/srv/fs/tmpfs/ Set the TMPFS root node's link count to 1.  
2756 5928 d 9 h jermar /trunk/uspace/srv/fs/tmpfs/ Introduce real link counts for TMPFS.  
2753 5931 d 7 h jermar /trunk/uspace/ Move canonify() to libc so that it can be used also on the libc side.  
2752 5931 d 14 h jermar /trunk/uspace/srv/vfs/ Make VFS canonify path names on lookup.  
2751 5932 d 12 h jermar /trunk/uspace/ Add canonify() for file system path canonization.
Not yet used by VFS.
 
2749 5934 d 7 h jermar /trunk/uspace/srv/vfs/ contents_rwlock should not be acquired as a futex but rather as a rwlock.  
2748 5934 d 7 h jermar /trunk/uspace/srv/vfs/ Support for O_TRUNC.  
2747 5935 d 6 h jermar /trunk/uspace/ Move the core lookup logic from TMPFS to libfs.  
2742 5937 d 6 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 5943 d 7 h jermar /trunk/uspace/srv/vfs/ Initialize the VFS node properly.  
2739 5943 d 7 h jermar /trunk/uspace/srv/fs/tmpfs/ Remove duplicate initialization.  
2736 5945 d 9 h jermar /trunk/uspace/srv/fs/tmpfs/ Unlink a TMPFS node more thoroughly.  
2735 5945 d 12 h jermar /trunk/uspace/ Support for rmdir(), unlink() and the respective VFS operations.  
2734 5945 d 14 h jermar /trunk/uspace/ Support for close().  
2733 5945 d 14 h jermar /trunk/uspace/ Add TMPFS support for destroying leaf links in the file system namespace.  
2732 5945 d 15 h jermar /trunk/uspace/srv/fs/tmpfs/ When freeing up a TMPFS node, it should also be removed from the dentries hash table.  
2731 5945 d 15 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 5946 d 17 h jermar /trunk/uspace/srv/ Introduce the notion of VFS node link counts.  
2728 5951 d 7 h jermar /trunk/uspace/srv/fs/tmpfs/ Descend vs. descent.  
2711 5966 d 10 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 5966 d 10 h jermar /trunk/uspace/ VFS_WRITE and tmpfs_write fixes.  
2709 5966 d 12 h jermar /trunk/uspace/srv/vfs/ VFS_OPEN and VFS_WRITE now understand O_APPEND.  
2708 5966 d 12 h jermar /trunk/uspace/ VFS_OPEN now understands O_CREAT and O_EXCL.  
2707 5966 d 14 h jermar /trunk/uspace/ Support for mkdir().  
2706 5966 d 18 h jermar /trunk/uspace/srv/fs/tmpfs/ Move handling of the miss on excessive components out of the main loop in
tmpfs_lookup.
 
2705 5967 d 6 h jermar /trunk/uspace/ More elegant, flexible and complete version of tmpfs_lookup.  
2704 5967 d 17 h jermar /trunk/uspace/srv/vfs/ Additional VFS lookup flags.  
2700 5974 d 15 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 5975 d 5 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 5975 d 11 h jermar /trunk/uspace/srv/vfs/ Small fix for VFS_TRUNCATE. Move lookup and registration code to separate
modules.
 
2693 5980 d 15 h jermar /trunk/uspace/ Add ftruncate() and support for VFS_TRUNCATE to VFS and TMPFS.  
2691 5984 d 9 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 5985 d 7 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.
 
2689 5985 d 8 h jermar /trunk/uspace/srv/vfs/ Merge all VFS operations into one file.  
2688 5985 d 8 h jermar /trunk/uspace/ Make uspace rwlock API naming conventions consistent with kernel rwlock API.  
2687 5985 d 8 h jermar /trunk/uspace/srv/ Management of the cached VFS node size.  
2686 5985 d 9 h jermar /trunk/uspace/srv/fs/tmpfs/ Previous commit was toxic. When emulating gaps, zero out the reallocated buffer, not the original one.  
2685 5985 d 9 h jermar /trunk/uspace/srv/fs/tmpfs/ TMPFS must handle file gaps.
