2884 5895 d 3 h jermar /trunk/uspace/srv/fs/fat/ merge vs. coalesce  
2881 5895 d 7 h jermar /trunk/uspace/srv/fs/fat/ Code for de/allocation of VFS indices for FAT.  
2876 5895 d 11 h jermar /trunk/uspace/srv/fs/fat/ Add a dedicated source file for handling FAT indices.  
2864 5909 d 1 h jermar /trunk/uspace/srv/fs/fat/ Introduce the foundation for unique and stable FAT VFS node indices.

The first two reserved FAT entries are physically present in each FAT, so fix
the code to be aware of this.		  
2863 5909 d 12 h jermar /trunk/uspace/ Revert libfs node_get() API to a model without the parent node pointer
argument.		  
2859 5914 d 17 h jermar /trunk/uspace/srv/fs/fat/ Add fat_block_get().  
2858 5914 d 20 h jermar /trunk/uspace/ libfs destroy operation should rather return an error code instead of a truth
value.		  
2857 5914 d 20 h jermar /trunk/uspace/ Add stubs for unimplemented FAT libfs operations.  
2856 5914 d 21 h jermar /trunk/uspace/srv/fs/fat/ Add a locking scheme for FAT in-core cache and nodes.  
2855 5914 d 22 h jermar /trunk/uspace/srv/fs/fat/ fat_node_put(). No locking so far.  
2852 5915 d 18 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.
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.		  
2845 5917 d 0 h jermar /trunk/uspace/srv/fs/fat/ Add fat_has_children(). Alse assume that fat_block_get() can never return NULL.  
2844 5917 d 1 h jermar /trunk/uspace/ Add fat_root_get() and fat_plb_get_char().  
2843 5917 d 2 h jermar /trunk/uspace/srv/fs/fat/ Somewhat complete implementation of fat_node_get().  
2831 5919 d 18 h jermar /trunk/uspace/ Commit progress on the FAT file system server implementation.  
2828 5920 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 5921 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 5926 d 3 h jermar /trunk/uspace/ Replace all endian.h in uspace with a copy of the kernel's respective byteorder.h.  
2796 5927 d 3 h jermar /trunk/uspace/srv/fs/fat/ Convert FAT on-disk metadata from little-endian to native representation.  
2793 5927 d 4 h jermar /trunk/uspace/srv/fs/fat/ First untested bits of FAT lookup support.  
2792 5927 d 4 h jermar /trunk/uspace/ libfs' node_get() operation does not need the file system handle.  
2791 5930 d 1 h jermar /trunk/uspace/ Make libfs_lookup() more generic.  
2789 5932 d 15 h jermar /trunk/uspace/srv/fs/fat/ Fix FAT boot sector definition and introduce the FAT in-core node type.  
2770 5949 d 3 h jermar /trunk/uspace/ Introduce fs_handle_t, dev_handle_t and fs_index_t.  
2763 5951 d 6 h jermar /trunk/uspace/ Support for rename().  
2760 5954 d 1 h jermar /trunk/uspace/ Support for multiple TMPFS node names.  
2758 5955 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 5955 d 3 h jermar /trunk/uspace/srv/fs/tmpfs/ Set the TMPFS root node's link count to 1.  
2756 5955 d 4 h jermar /trunk/uspace/srv/fs/tmpfs/ Introduce real link counts for TMPFS.  
2747 5962 d 1 h jermar /trunk/uspace/ Move the core lookup logic from TMPFS to libfs.  
2742 5964 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 5970 d 1 h jermar /trunk/uspace/srv/fs/tmpfs/ Remove duplicate initialization.  
2736 5972 d 3 h jermar /trunk/uspace/srv/fs/tmpfs/ Unlink a TMPFS node more thoroughly.  
2735 5972 d 7 h jermar /trunk/uspace/ Support for rmdir(), unlink() and the respective VFS operations.  
2733 5972 d 9 h jermar /trunk/uspace/ Add TMPFS support for destroying leaf links in the file system namespace.  
2732 5972 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 5972 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 5973 d 12 h jermar /trunk/uspace/srv/ Introduce the notion of VFS node link counts.  
2728 5978 d 1 h jermar /trunk/uspace/srv/fs/tmpfs/ Descend vs. descent.  
2711 5993 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.
