2884 5901 d 2 h jermar /trunk/uspace/srv/fs/fat/ merge vs. coalesce  
2881 5901 d 7 h jermar /trunk/uspace/srv/fs/fat/ Code for de/allocation of VFS indices for FAT.  
2876 5901 d 10 h jermar /trunk/uspace/srv/fs/fat/ Add a dedicated source file for handling FAT indices.  
2864 5915 d 0 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 5915 d 12 h jermar /trunk/uspace/ Revert libfs node_get() API to a model without the parent node pointer
argument.		  
2859 5920 d 17 h jermar /trunk/uspace/srv/fs/fat/ Add fat_block_get().  
2858 5920 d 20 h jermar /trunk/uspace/ libfs destroy operation should rather return an error code instead of a truth
value.		  
2857 5920 d 20 h jermar /trunk/uspace/ Add stubs for unimplemented FAT libfs operations.  
2856 5920 d 20 h jermar /trunk/uspace/srv/fs/fat/ Add a locking scheme for FAT in-core cache and nodes.  
2855 5920 d 21 h jermar /trunk/uspace/srv/fs/fat/ fat_node_put(). No locking so far.  
2852 5921 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 5923 d 0 h jermar /trunk/uspace/srv/fs/fat/ Add fat_has_children(). Alse assume that fat_block_get() can never return NULL.  
2844 5923 d 0 h jermar /trunk/uspace/ Add fat_root_get() and fat_plb_get_char().  
2843 5923 d 1 h jermar /trunk/uspace/srv/fs/fat/ Somewhat complete implementation of fat_node_get().  
2831 5925 d 18 h jermar /trunk/uspace/ Commit progress on the FAT file system server implementation.  
2828 5926 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 5927 d 22 h jermar /trunk/uspace/srv/fs/fat/ Introduce and also use the foundation of block cache API in FAT's match
operation.		  
2821 5927 d 22 h jermar /trunk/uspace/srv/vfs/ Update comment.  
2798 5932 d 2 h jermar /trunk/uspace/ Replace all endian.h in uspace with a copy of the kernel's respective byteorder.h.  
2796 5933 d 2 h jermar /trunk/uspace/srv/fs/fat/ Convert FAT on-disk metadata from little-endian to native representation.  
2793 5933 d 3 h jermar /trunk/uspace/srv/fs/fat/ First untested bits of FAT lookup support.  
2792 5933 d 3 h jermar /trunk/uspace/ libfs' node_get() operation does not need the file system handle.  
2791 5936 d 1 h jermar /trunk/uspace/ Make libfs_lookup() more generic.  
2789 5938 d 14 h jermar /trunk/uspace/srv/fs/fat/ Fix FAT boot sector definition and introduce the FAT in-core node type.  
2788 5938 d 15 h jermar /trunk/uspace/ Return EBUSY if trying to mount something over an already mounted root FS.
(Contributed by Tim Post)		  
2770 5955 d 2 h jermar /trunk/uspace/ Introduce fs_handle_t, dev_handle_t and fs_index_t.  
2769 5956 d 1 h jermar /trunk/uspace/srv/vfs/ VFS index needs to be treated as uint64_t.  
2768 5956 d 3 h jermar /trunk/uspace/srv/vfs/ Fibril serialization is required when two file systems register contemporarily.  
2766 5957 d 3 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 5957 d 6 h jermar /trunk/uspace/ Support for rename().  
2760 5960 d 1 h jermar /trunk/uspace/ Support for multiple TMPFS node names.  
2758 5961 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 5961 d 2 h jermar /trunk/uspace/srv/fs/tmpfs/ Set the TMPFS root node's link count to 1.  
2756 5961 d 3 h jermar /trunk/uspace/srv/fs/tmpfs/ Introduce real link counts for TMPFS.  
2753 5964 d 2 h jermar /trunk/uspace/ Move canonify() to libc so that it can be used also on the libc side.  
2752 5964 d 8 h jermar /trunk/uspace/srv/vfs/ Make VFS canonify path names on lookup.  
2751 5965 d 6 h jermar /trunk/uspace/ Add canonify() for file system path canonization.
Not yet used by VFS.		  
2749 5967 d 1 h jermar /trunk/uspace/srv/vfs/ contents_rwlock should not be acquired as a futex but rather as a rwlock.  
2748 5967 d 2 h jermar /trunk/uspace/srv/vfs/ Support for O_TRUNC.  
2747 5968 d 0 h jermar /trunk/uspace/ Move the core lookup logic from TMPFS to libfs.
