2831 5945 d 13 h jermar /trunk/uspace/ Commit progress on the FAT file system server implementation.  
2828 5946 d 17 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 5947 d 17 h jermar /trunk/uspace/srv/fs/fat/ Introduce and also use the foundation of block cache API in FAT's match
operation.		  
2821 5947 d 17 h jermar /trunk/uspace/srv/vfs/ Update comment.  
2798 5951 d 22 h jermar /trunk/uspace/ Replace all endian.h in uspace with a copy of the kernel's respective byteorder.h.  
2796 5952 d 22 h jermar /trunk/uspace/srv/fs/fat/ Convert FAT on-disk metadata from little-endian to native representation.  
2793 5952 d 23 h jermar /trunk/uspace/srv/fs/fat/ First untested bits of FAT lookup support.  
2792 5952 d 23 h jermar /trunk/uspace/ libfs' node_get() operation does not need the file system handle.  
2791 5955 d 20 h jermar /trunk/uspace/ Make libfs_lookup() more generic.  
2789 5958 d 10 h jermar /trunk/uspace/srv/fs/fat/ Fix FAT boot sector definition and introduce the FAT in-core node type.  
2788 5958 d 11 h jermar /trunk/uspace/ Return EBUSY if trying to mount something over an already mounted root FS.
(Contributed by Tim Post)		  
2770 5974 d 22 h jermar /trunk/uspace/ Introduce fs_handle_t, dev_handle_t and fs_index_t.  
2769 5975 d 20 h jermar /trunk/uspace/srv/vfs/ VFS index needs to be treated as uint64_t.  
2768 5975 d 22 h jermar /trunk/uspace/srv/vfs/ Fibril serialization is required when two file systems register contemporarily.  
2766 5976 d 22 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 5977 d 1 h jermar /trunk/uspace/ Support for rename().  
2760 5979 d 20 h jermar /trunk/uspace/ Support for multiple TMPFS node names.  
2758 5980 d 20 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 5980 d 22 h jermar /trunk/uspace/srv/fs/tmpfs/ Set the TMPFS root node's link count to 1.  
2756 5980 d 23 h jermar /trunk/uspace/srv/fs/tmpfs/ Introduce real link counts for TMPFS.  
2753 5983 d 21 h jermar /trunk/uspace/ Move canonify() to libc so that it can be used also on the libc side.  
2752 5984 d 3 h jermar /trunk/uspace/srv/vfs/ Make VFS canonify path names on lookup.  
2751 5985 d 1 h jermar /trunk/uspace/ Add canonify() for file system path canonization.
Not yet used by VFS.		  
2749 5986 d 21 h jermar /trunk/uspace/srv/vfs/ contents_rwlock should not be acquired as a futex but rather as a rwlock.  
2748 5986 d 21 h jermar /trunk/uspace/srv/vfs/ Support for O_TRUNC.  
2747 5987 d 20 h jermar /trunk/uspace/ Move the core lookup logic from TMPFS to libfs.  
2742 5989 d 20 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 5995 d 20 h jermar /trunk/uspace/srv/vfs/ Initialize the VFS node properly.  
2739 5995 d 20 h jermar /trunk/uspace/srv/fs/tmpfs/ Remove duplicate initialization.  
2736 5997 d 22 h jermar /trunk/uspace/srv/fs/tmpfs/ Unlink a TMPFS node more thoroughly.  
2735 5998 d 2 h jermar /trunk/uspace/ Support for rmdir(), unlink() and the respective VFS operations.  
2734 5998 d 4 h jermar /trunk/uspace/ Support for close().  
2733 5998 d 4 h jermar /trunk/uspace/ Add TMPFS support for destroying leaf links in the file system namespace.  
2732 5998 d 4 h jermar /trunk/uspace/srv/fs/tmpfs/ When freeing up a TMPFS node, it should also be removed from the dentries hash table.  
2731 5998 d 5 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 5999 d 7 h jermar /trunk/uspace/srv/ Introduce the notion of VFS node link counts.  
2728 6003 d 20 h jermar /trunk/uspace/srv/fs/tmpfs/ Descend vs. descent.  
2711 6018 d 23 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 6019 d 0 h jermar /trunk/uspace/ VFS_WRITE and tmpfs_write fixes.  
2709 6019 d 2 h jermar /trunk/uspace/srv/vfs/ VFS_OPEN and VFS_WRITE now understand O_APPEND.
