2857 5905 d 18 h jermar /trunk/uspace/ Add stubs for unimplemented FAT libfs operations.  
2856 5905 d 18 h jermar /trunk/uspace/srv/fs/fat/ Add a locking scheme for FAT in-core cache and nodes.  
2855 5905 d 19 h jermar /trunk/uspace/srv/fs/fat/ fat_node_put(). No locking so far.  
2852 5906 d 16 h jermar /trunk/uspace/ Add node_put() to libfs operations and instrument libfs_lookup() to use it at
appropriate places.
Add node_put() to libfs operations and instrument libfs_lookup() to use it at
appropriate places.
Add node_put() to libfs operations and instrument libfs_lookup() to use it at
appropriate places.

appropriate places.

Add node_put() to libfs operations and instrument libfs_lookup() to use it at
appropriate places.		  
2845 5907 d 22 h jermar /trunk/uspace/srv/fs/fat/ Add fat_has_children(). Alse assume that fat_block_get() can never return NULL.  
2844 5907 d 22 h jermar /trunk/uspace/ Add fat_root_get() and fat_plb_get_char().  
2843 5907 d 23 h jermar /trunk/uspace/srv/fs/fat/ Somewhat complete implementation of fat_node_get().  
2831 5910 d 16 h jermar /trunk/uspace/ Commit progress on the FAT file system server implementation.  
2828 5911 d 20 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 5912 d 20 h jermar /trunk/uspace/srv/fs/fat/ Introduce and also use the foundation of block cache API in FAT's match
operation.		  
2821 5912 d 20 h jermar /trunk/uspace/srv/vfs/ Update comment.  
2798 5917 d 0 h jermar /trunk/uspace/ Replace all endian.h in uspace with a copy of the kernel's respective byteorder.h.  
2796 5918 d 0 h jermar /trunk/uspace/srv/fs/fat/ Convert FAT on-disk metadata from little-endian to native representation.  
2793 5918 d 1 h jermar /trunk/uspace/srv/fs/fat/ First untested bits of FAT lookup support.  
2792 5918 d 1 h jermar /trunk/uspace/ libfs' node_get() operation does not need the file system handle.  
2791 5920 d 23 h jermar /trunk/uspace/ Make libfs_lookup() more generic.  
2789 5923 d 12 h jermar /trunk/uspace/srv/fs/fat/ Fix FAT boot sector definition and introduce the FAT in-core node type.  
2788 5923 d 13 h jermar /trunk/uspace/ Return EBUSY if trying to mount something over an already mounted root FS.
(Contributed by Tim Post)		  
2770 5940 d 1 h jermar /trunk/uspace/ Introduce fs_handle_t, dev_handle_t and fs_index_t.  
2769 5940 d 23 h jermar /trunk/uspace/srv/vfs/ VFS index needs to be treated as uint64_t.  
2768 5941 d 1 h jermar /trunk/uspace/srv/vfs/ Fibril serialization is required when two file systems register contemporarily.  
2766 5942 d 1 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 5942 d 4 h jermar /trunk/uspace/ Support for rename().  
2760 5944 d 23 h jermar /trunk/uspace/ Support for multiple TMPFS node names.  
2758 5945 d 23 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 5946 d 0 h jermar /trunk/uspace/srv/fs/tmpfs/ Set the TMPFS root node's link count to 1.  
2756 5946 d 1 h jermar /trunk/uspace/srv/fs/tmpfs/ Introduce real link counts for TMPFS.  
2753 5949 d 0 h jermar /trunk/uspace/ Move canonify() to libc so that it can be used also on the libc side.  
2752 5949 d 6 h jermar /trunk/uspace/srv/vfs/ Make VFS canonify path names on lookup.  
2751 5950 d 4 h jermar /trunk/uspace/ Add canonify() for file system path canonization.
Not yet used by VFS.		  
2749 5951 d 23 h jermar /trunk/uspace/srv/vfs/ contents_rwlock should not be acquired as a futex but rather as a rwlock.  
2748 5952 d 0 h jermar /trunk/uspace/srv/vfs/ Support for O_TRUNC.  
2747 5952 d 22 h jermar /trunk/uspace/ Move the core lookup logic from TMPFS to libfs.  
2742 5954 d 23 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 5960 d 23 h jermar /trunk/uspace/srv/vfs/ Initialize the VFS node properly.  
2739 5960 d 23 h jermar /trunk/uspace/srv/fs/tmpfs/ Remove duplicate initialization.  
2736 5963 d 1 h jermar /trunk/uspace/srv/fs/tmpfs/ Unlink a TMPFS node more thoroughly.  
2735 5963 d 5 h jermar /trunk/uspace/ Support for rmdir(), unlink() and the respective VFS operations.  
2734 5963 d 6 h jermar /trunk/uspace/ Support for close().  
2733 5963 d 7 h jermar /trunk/uspace/ Add TMPFS support for destroying leaf links in the file system namespace.
