2852 5935 d 20 h jermar /trunk/uspace/ Add node_put() to libfs operations and instrument libfs_lookup() to use it at
appropriate places.

2845 5937 d 2 h jermar /trunk/uspace/srv/fs/fat/ Add fat_has_children(). Alse assume that fat_block_get() can never return NULL.  
2844 5937 d 3 h jermar /trunk/uspace/ Add fat_root_get() and fat_plb_get_char().  
2843 5937 d 4 h jermar /trunk/uspace/srv/fs/fat/ Somewhat complete implementation of fat_node_get().  
2831 5939 d 20 h jermar /trunk/uspace/ Commit progress on the FAT file system server implementation.  
2828 5941 d 1 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 5942 d 0 h jermar /trunk/uspace/srv/fs/fat/ Introduce and also use the foundation of block cache API in FAT's match
operation.		  
2821 5942 d 0 h jermar /trunk/uspace/srv/vfs/ Update comment.  
2798 5946 d 5 h jermar /trunk/uspace/ Replace all endian.h in uspace with a copy of the kernel's respective byteorder.h.  
2796 5947 d 5 h jermar /trunk/uspace/srv/fs/fat/ Convert FAT on-disk metadata from little-endian to native representation.  
2793 5947 d 6 h jermar /trunk/uspace/srv/fs/fat/ First untested bits of FAT lookup support.  
2792 5947 d 6 h jermar /trunk/uspace/ libfs' node_get() operation does not need the file system handle.  
2791 5950 d 3 h jermar /trunk/uspace/ Make libfs_lookup() more generic.  
2789 5952 d 17 h jermar /trunk/uspace/srv/fs/fat/ Fix FAT boot sector definition and introduce the FAT in-core node type.  
2788 5952 d 18 h jermar /trunk/uspace/ Return EBUSY if trying to mount something over an already mounted root FS.
(Contributed by Tim Post)		  
2770 5969 d 5 h jermar /trunk/uspace/ Introduce fs_handle_t, dev_handle_t and fs_index_t.  
2769 5970 d 4 h jermar /trunk/uspace/srv/vfs/ VFS index needs to be treated as uint64_t.  
2768 5970 d 6 h jermar /trunk/uspace/srv/vfs/ Fibril serialization is required when two file systems register contemporarily.  
2766 5971 d 6 h jermar /trunk/uspace/srv/vfs/ Grab the nodes_futex when manipulating node link counts in rename() and
_unlink().

Fix VFS futex definitions and declarations by replacing atomic_t by futex_t.		  
2763 5971 d 8 h jermar /trunk/uspace/ Support for rename().  
2760 5974 d 3 h jermar /trunk/uspace/ Support for multiple TMPFS node names.  
2758 5975 d 3 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 5975 d 5 h jermar /trunk/uspace/srv/fs/tmpfs/ Set the TMPFS root node's link count to 1.  
2756 5975 d 6 h jermar /trunk/uspace/srv/fs/tmpfs/ Introduce real link counts for TMPFS.  
2753 5978 d 4 h jermar /trunk/uspace/ Move canonify() to libc so that it can be used also on the libc side.  
2752 5978 d 11 h jermar /trunk/uspace/srv/vfs/ Make VFS canonify path names on lookup.  
2751 5979 d 9 h jermar /trunk/uspace/ Add canonify() for file system path canonization.
Not yet used by VFS.		  
2749 5981 d 4 h jermar /trunk/uspace/srv/vfs/ contents_rwlock should not be acquired as a futex but rather as a rwlock.  
2748 5981 d 4 h jermar /trunk/uspace/srv/vfs/ Support for O_TRUNC.  
2747 5982 d 3 h jermar /trunk/uspace/ Move the core lookup logic from TMPFS to libfs.  
2742 5984 d 3 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().		  
2740 5990 d 4 h jermar /trunk/uspace/srv/vfs/ Initialize the VFS node properly.  
2739 5990 d 4 h jermar /trunk/uspace/srv/fs/tmpfs/ Remove duplicate initialization.  
2736 5992 d 6 h jermar /trunk/uspace/srv/fs/tmpfs/ Unlink a TMPFS node more thoroughly.  
2735 5992 d 9 h jermar /trunk/uspace/ Support for rmdir(), unlink() and the respective VFS operations.  
2734 5992 d 11 h jermar /trunk/uspace/ Support for close().  
2733 5992 d 11 h jermar /trunk/uspace/ Add TMPFS support for destroying leaf links in the file system namespace.  
2732 5992 d 12 h jermar /trunk/uspace/srv/fs/tmpfs/ When freeing up a TMPFS node, it should also be removed from the dentries hash table.  
2731 5992 d 12 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 5993 d 14 h jermar /trunk/uspace/srv/ Introduce the notion of VFS node link counts.
