2852 5930 d 1 h jermar /trunk/uspace/ Add node_put() to libfs operations and instrument libfs_lookup() to use it at
appropriate places.

2845 5931 d 7 h jermar /trunk/uspace/srv/fs/fat/ Add fat_has_children(). Alse assume that fat_block_get() can never return NULL.  
2844 5931 d 8 h jermar /trunk/uspace/ Add fat_root_get() and fat_plb_get_char().  
2843 5931 d 9 h jermar /trunk/uspace/srv/fs/fat/ Somewhat complete implementation of fat_node_get().  
2831 5934 d 1 h jermar /trunk/uspace/ Commit progress on the FAT file system server implementation.  
2828 5935 d 5 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 5936 d 5 h jermar /trunk/uspace/srv/fs/fat/ Introduce and also use the foundation of block cache API in FAT's match
operation.		  
2798 5940 d 10 h jermar /trunk/uspace/ Replace all endian.h in uspace with a copy of the kernel's respective byteorder.h.  
2796 5941 d 10 h jermar /trunk/uspace/srv/fs/fat/ Convert FAT on-disk metadata from little-endian to native representation.  
2793 5941 d 11 h jermar /trunk/uspace/srv/fs/fat/ First untested bits of FAT lookup support.  
2792 5941 d 11 h jermar /trunk/uspace/ libfs' node_get() operation does not need the file system handle.  
2791 5944 d 8 h jermar /trunk/uspace/ Make libfs_lookup() more generic.  
2789 5946 d 22 h jermar /trunk/uspace/srv/fs/fat/ Fix FAT boot sector definition and introduce the FAT in-core node type.  
2770 5963 d 10 h jermar /trunk/uspace/ Introduce fs_handle_t, dev_handle_t and fs_index_t.  
2763 5965 d 13 h jermar /trunk/uspace/ Support for rename().  
2760 5968 d 8 h jermar /trunk/uspace/ Support for multiple TMPFS node names.  
2758 5969 d 8 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 5969 d 10 h jermar /trunk/uspace/srv/fs/tmpfs/ Set the TMPFS root node's link count to 1.  
2756 5969 d 11 h jermar /trunk/uspace/srv/fs/tmpfs/ Introduce real link counts for TMPFS.  
2747 5976 d 8 h jermar /trunk/uspace/ Move the core lookup logic from TMPFS to libfs.  
2742 5978 d 8 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 5984 d 8 h jermar /trunk/uspace/srv/fs/tmpfs/ Remove duplicate initialization.  
2736 5986 d 10 h jermar /trunk/uspace/srv/fs/tmpfs/ Unlink a TMPFS node more thoroughly.  
2735 5986 d 14 h jermar /trunk/uspace/ Support for rmdir(), unlink() and the respective VFS operations.  
2733 5986 d 16 h jermar /trunk/uspace/ Add TMPFS support for destroying leaf links in the file system namespace.  
2732 5986 d 16 h jermar /trunk/uspace/srv/fs/tmpfs/ When freeing up a TMPFS node, it should also be removed from the dentries hash table.  
2731 5986 d 17 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 5987 d 19 h jermar /trunk/uspace/srv/ Introduce the notion of VFS node link counts.  
2728 5992 d 8 h jermar /trunk/uspace/srv/fs/tmpfs/ Descend vs. descent.  
2711 6007 d 11 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 6007 d 11 h jermar /trunk/uspace/ VFS_WRITE and tmpfs_write fixes.  
2707 6007 d 15 h jermar /trunk/uspace/ Support for mkdir().  
2706 6007 d 20 h jermar /trunk/uspace/srv/fs/tmpfs/ Move handling of the miss on excessive components out of the main loop in
tmpfs_lookup.		  
2705 6008 d 8 h jermar /trunk/uspace/ More elegant, flexible and complete version of tmpfs_lookup.  
2700 6015 d 17 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 6016 d 7 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 6021 d 17 h jermar /trunk/uspace/ Add ftruncate() and support for VFS_TRUNCATE to VFS and TMPFS.  
2690 6026 d 8 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 6026 d 10 h jermar /trunk/uspace/srv/ Management of the cached VFS node size.  
2686 6026 d 11 h jermar /trunk/uspace/srv/fs/tmpfs/ Previous commit was toxic. When emulating gaps, zero out the reallocated buffer, not the original one.
