2763 5927 d 9 h jermar /trunk/uspace/ Support for rename().  
2760 5930 d 4 h jermar /trunk/uspace/ Support for multiple TMPFS node names.  
2758 5931 d 5 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 5931 d 6 h jermar /trunk/uspace/srv/fs/tmpfs/ Set the TMPFS root node's link count to 1.  
2756 5931 d 7 h jermar /trunk/uspace/srv/fs/tmpfs/ Introduce real link counts for TMPFS.  
2747 5938 d 4 h jermar /trunk/uspace/ Move the core lookup logic from TMPFS to libfs.  
2742 5940 d 4 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().
 
2739 5946 d 5 h jermar /trunk/uspace/srv/fs/tmpfs/ Remove duplicate initialization.  
2736 5948 d 7 h jermar /trunk/uspace/srv/fs/tmpfs/ Unlink a TMPFS node more thoroughly.  
2735 5948 d 10 h jermar /trunk/uspace/ Support for rmdir(), unlink() and the respective VFS operations.  
2733 5948 d 12 h jermar /trunk/uspace/ Add TMPFS support for destroying leaf links in the file system namespace.  
2732 5948 d 13 h jermar /trunk/uspace/srv/fs/tmpfs/ When freeing up a TMPFS node, it should also be removed from the dentries hash table.  
2731 5948 d 13 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 5949 d 15 h jermar /trunk/uspace/srv/ Introduce the notion of VFS node link counts.  
2728 5954 d 5 h jermar /trunk/uspace/srv/fs/tmpfs/ Descend vs. descent.  
2711 5969 d 8 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 5969 d 8 h jermar /trunk/uspace/ VFS_WRITE and tmpfs_write fixes.  
2707 5969 d 12 h jermar /trunk/uspace/ Support for mkdir().  
2706 5969 d 16 h jermar /trunk/uspace/srv/fs/tmpfs/ Move handling of the miss on excessive components out of the main loop in
tmpfs_lookup.
 
2705 5970 d 4 h jermar /trunk/uspace/ More elegant, flexible and complete version of tmpfs_lookup.  
2700 5977 d 13 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 5978 d 3 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.
 
2693 5983 d 13 h jermar /trunk/uspace/ Add ftruncate() and support for VFS_TRUNCATE to VFS and TMPFS.  
2690 5988 d 5 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 5988 d 6 h jermar /trunk/uspace/srv/ Management of the cached VFS node size.  
2686 5988 d 7 h jermar /trunk/uspace/srv/fs/tmpfs/ Previous commit was toxic. When emulating gaps, zero out the reallocated buffer, not the original one.  
2685 5988 d 7 h jermar /trunk/uspace/srv/fs/tmpfs/ TMPFS must handle file gaps.  
2678 5996 d 9 h jermar /trunk/uspace/ The IPC_M_SHARE_* and IPC_M_DATA_* calls pass through 3 stages. Rename the send,
receive and deliver wrappers to names ending with 'start', 'receive' and
'finalize', respectively. This should make it clearer for dummies.
 
2676 5996 d 17 h jermar /trunk/ Simplify the IPC_M_DATA_WRITE protocol. Do not pass the source address space
virtual address to the recipient. This feature was not used anyway. Now
IPC_M_DATA_WRITE and IPC_M_DATA_READ are feature-aligned.
 
2673 5997 d 6 h jermar /trunk/uspace/srv/fs/tmpfs/ Rename variable from 'size' to 'len'.  
2667 6002 d 2 h jermar /trunk/uspace/srv/fs/tmpfs/ The previous commit was not entirely sane.
Handle VFS_WRITE correctly when the file doesn't grow.
Handle it correctly also when the file grows.
 
2666 6002 d 7 h jermar /trunk/uspace/srv/ VFS and TMPFS support for VFS_WRITE.  
2664 6004 d 4 h jermar /trunk/uspace/srv/fs/tmpfs/ Fix two bugs in TMPFS-side VFS_READ.  
2663 6004 d 5 h jermar /trunk/uspace/ Reimplement VFS_READ using IPC_M_DATA_READ.  
2658 6005 d 4 h jermar /trunk/uspace/srv/ VFS work.
Foundation for TMPFS-side VFS_READ and fixes in VFS-side VFS_READ.
 
2655 6008 d 10 h jermar /trunk/uspace/srv/fs/tmpfs/ TMPFS work.
VFS_LOOKUP implemented.
 
2645 6011 d 9 h jermar /trunk/uspace/ Start TMPFS.
Not loaded during boot as there is a reproducible kernel panic which occurs when
both tmpfs and fat are loaded.
 
2644 6011 d 10 h jermar /trunk/uspace/ Move incomplete fs interface from fat.h to libfs.  
2643 6011 d 10 h jermar /trunk/uspace/ VFS work.
Move FS registration code to libfs.
 
2639 6022 d 4 h jermar /trunk/uspace/srv/fs/fat/ FAT work.
Foundation for FAT dentry comparison function.
Beware of looking at the diff or risk loosing sanity.
