2845 5958 d 0 h jermar /trunk/uspace/srv/fs/fat/ Add fat_has_children(). Alse assume that fat_block_get() can never return NULL.  
2844 5958 d 1 h jermar /trunk/uspace/ Add fat_root_get() and fat_plb_get_char().  
2843 5958 d 2 h jermar /trunk/uspace/srv/fs/fat/ Somewhat complete implementation of fat_node_get().  
2831 5960 d 18 h jermar /trunk/uspace/ Commit progress on the FAT file system server implementation.  
2828 5961 d 22 h jermar /trunk/uspace/srv/fs/fat/ BPS read from FAT bootsector is little-endian. It must converted to host
endianity before being used.
 
2822 5962 d 22 h jermar /trunk/uspace/srv/fs/fat/ Introduce and also use the foundation of block cache API in FAT's match
operation.
 
2798 5967 d 3 h jermar /trunk/uspace/ Replace all endian.h in uspace with a copy of the kernel's respective byteorder.h.  
2796 5968 d 3 h jermar /trunk/uspace/srv/fs/fat/ Convert FAT on-disk metadata from little-endian to native representation.  
2793 5968 d 4 h jermar /trunk/uspace/srv/fs/fat/ First untested bits of FAT lookup support.  
2792 5968 d 4 h jermar /trunk/uspace/ libfs' node_get() operation does not need the file system handle.  
2791 5971 d 1 h jermar /trunk/uspace/ Make libfs_lookup() more generic.  
2789 5973 d 15 h jermar /trunk/uspace/srv/fs/fat/ Fix FAT boot sector definition and introduce the FAT in-core node type.  
2770 5990 d 3 h jermar /trunk/uspace/ Introduce fs_handle_t, dev_handle_t and fs_index_t.  
2763 5992 d 6 h jermar /trunk/uspace/ Support for rename().  
2760 5995 d 1 h jermar /trunk/uspace/ Support for multiple TMPFS node names.  
2758 5996 d 1 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 5996 d 3 h jermar /trunk/uspace/srv/fs/tmpfs/ Set the TMPFS root node's link count to 1.  
2756 5996 d 4 h jermar /trunk/uspace/srv/fs/tmpfs/ Introduce real link counts for TMPFS.  
2747 6003 d 1 h jermar /trunk/uspace/ Move the core lookup logic from TMPFS to libfs.  
2742 6005 d 1 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 6011 d 1 h jermar /trunk/uspace/srv/fs/tmpfs/ Remove duplicate initialization.  
2736 6013 d 3 h jermar /trunk/uspace/srv/fs/tmpfs/ Unlink a TMPFS node more thoroughly.  
2735 6013 d 7 h jermar /trunk/uspace/ Support for rmdir(), unlink() and the respective VFS operations.  
2733 6013 d 9 h jermar /trunk/uspace/ Add TMPFS support for destroying leaf links in the file system namespace.  
2732 6013 d 9 h jermar /trunk/uspace/srv/fs/tmpfs/ When freeing up a TMPFS node, it should also be removed from the dentries hash table.  
2731 6013 d 10 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 6014 d 12 h jermar /trunk/uspace/srv/ Introduce the notion of VFS node link counts.  
2728 6019 d 1 h jermar /trunk/uspace/srv/fs/tmpfs/ Descend vs. descent.  
2711 6034 d 4 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 6034 d 5 h jermar /trunk/uspace/ VFS_WRITE and tmpfs_write fixes.  
2707 6034 d 8 h jermar /trunk/uspace/ Support for mkdir().  
2706 6034 d 13 h jermar /trunk/uspace/srv/fs/tmpfs/ Move handling of the miss on excessive components out of the main loop in
tmpfs_lookup.
 
2705 6035 d 1 h jermar /trunk/uspace/ More elegant, flexible and complete version of tmpfs_lookup.  
2700 6042 d 10 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 6043 d 0 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 6048 d 10 h jermar /trunk/uspace/ Add ftruncate() and support for VFS_TRUNCATE to VFS and TMPFS.  
2690 6053 d 1 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 6053 d 3 h jermar /trunk/uspace/srv/ Management of the cached VFS node size.  
2686 6053 d 4 h jermar /trunk/uspace/srv/fs/tmpfs/ Previous commit was toxic. When emulating gaps, zero out the reallocated buffer, not the original one.  
2685 6053 d 4 h jermar /trunk/uspace/srv/fs/tmpfs/ TMPFS must handle file gaps.
