2766 5898 d 2 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 5898 d 5 h jermar /trunk/uspace/ Support for rename().  
2752 5905 d 7 h jermar /trunk/uspace/srv/vfs/ Make VFS canonify path names on lookup.  
2742 5911 d 0 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().		  
2735 5919 d 6 h jermar /trunk/uspace/ Support for rmdir(), unlink() and the respective VFS operations.  
2734 5919 d 7 h jermar /trunk/uspace/ Support for close().  
2731 5919 d 9 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 5920 d 11 h jermar /trunk/uspace/srv/ Introduce the notion of VFS node link counts.  
2709 5940 d 6 h jermar /trunk/uspace/srv/vfs/ VFS_OPEN and VFS_WRITE now understand O_APPEND.  
2707 5940 d 7 h jermar /trunk/uspace/ Support for mkdir().  
2704 5941 d 10 h jermar /trunk/uspace/srv/vfs/ Additional VFS lookup flags.  
2700 5948 d 9 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).		  
2693 5954 d 9 h jermar /trunk/uspace/ Add ftruncate() and support for VFS_TRUNCATE to VFS and TMPFS.  
2691 5958 d 2 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 5959 d 0 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.		  
2687 5959 d 2 h jermar /trunk/uspace/srv/ Management of the cached VFS node size.  
2684 5961 d 3 h jermar /trunk/ Add libc and VFS implementation of lseek(), VFS_SEEK resp.
Add the size member to the VFS node structure (not yet initialized).		  
2683 5961 d 6 h jermar /trunk/uspace/srv/vfs/ Introduce the open file lock. Modify vfs_rdwr() to take this lock into account
when reading or writing from/to an open file.		  
2682 5961 d 8 h jermar /trunk/uspace/ Fix type in declaration of VFS node rwlock.
Introduce a dedicated type for futexes. Make the existing futex code use this
newly introduced type and fix formatting in futex.c.		  
2681 5961 d 9 h jermar /trunk/uspace/ Turn the namespace futex into rwlock.
