2708 5994 d 0 h jermar /trunk/uspace/ VFS_OPEN now understands O_CREAT and O_EXCL.  
2707 5994 d 2 h jermar /trunk/uspace/ Support for mkdir().  
2706 5994 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 5994 d 18 h jermar /trunk/uspace/ More elegant, flexible and complete version of tmpfs_lookup.  
2704 5995 d 5 h jermar /trunk/uspace/srv/vfs/ Additional VFS lookup flags.  
2700 6002 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 6002 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 6002 d 23 h jermar /trunk/uspace/srv/vfs/ Small fix for VFS_TRUNCATE. Move lookup and registration code to separate
modules.		  
2693 6008 d 3 h jermar /trunk/uspace/ Add ftruncate() and support for VFS_TRUNCATE to VFS and TMPFS.  
2691 6011 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 6012 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.		  
2689 6012 d 20 h jermar /trunk/uspace/srv/vfs/ Merge all VFS operations into one file.  
2688 6012 d 20 h jermar /trunk/uspace/ Make uspace rwlock API naming conventions consistent with kernel rwlock API.  
2687 6012 d 20 h jermar /trunk/uspace/srv/ Management of the cached VFS node size.  
2686 6012 d 21 h jermar /trunk/uspace/srv/fs/tmpfs/ Previous commit was toxic. When emulating gaps, zero out the reallocated buffer, not the original one.  
2685 6012 d 21 h jermar /trunk/uspace/srv/fs/tmpfs/ TMPFS must handle file gaps.  
2684 6014 d 21 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 6015 d 0 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 6015 d 3 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 6015 d 4 h jermar /trunk/uspace/ Turn the namespace futex into rwlock.
