2734 5963 d 18 h jermar /trunk/uspace/ Support for close().  
2731 5963 d 19 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 5964 d 21 h jermar /trunk/uspace/srv/ Introduce the notion of VFS node link counts.  
2710 5984 d 14 h jermar /trunk/uspace/ VFS_WRITE and tmpfs_write fixes.  
2709 5984 d 16 h jermar /trunk/uspace/srv/vfs/ VFS_OPEN and VFS_WRITE now understand O_APPEND.  
2708 5984 d 16 h jermar /trunk/uspace/ VFS_OPEN now understands O_CREAT and O_EXCL.  
2707 5984 d 18 h jermar /trunk/uspace/ Support for mkdir().  
2704 5985 d 21 h jermar /trunk/uspace/srv/vfs/ Additional VFS lookup flags.  
2700 5992 d 19 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).		  
2698 5993 d 15 h jermar /trunk/uspace/srv/vfs/ Small fix for VFS_TRUNCATE. Move lookup and registration code to separate
modules.		  
2693 5998 d 19 h jermar /trunk/uspace/ Add ftruncate() and support for VFS_TRUNCATE to VFS and TMPFS.  
2691 6002 d 13 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 6003 d 11 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 6003 d 12 h jermar /trunk/uspace/srv/vfs/ Merge all VFS operations into one file.  
2688 6003 d 12 h jermar /trunk/uspace/ Make uspace rwlock API naming conventions consistent with kernel rwlock API.  
2687 6003 d 12 h jermar /trunk/uspace/srv/ Management of the cached VFS node size.  
2684 6005 d 13 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 6005 d 16 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 6005 d 19 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 6005 d 20 h jermar /trunk/uspace/ Turn the namespace futex into rwlock.
