2831 5902 d 11 h jermar /trunk/uspace/ Commit progress on the FAT file system server implementation.  
2828 5903 d 15 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 5904 d 15 h jermar /trunk/uspace/srv/fs/fat/ Introduce and also use the foundation of block cache API in FAT's match
operation.		  
2821 5904 d 15 h jermar /trunk/uspace/srv/vfs/ Update comment.  
2798 5908 d 19 h jermar /trunk/uspace/ Replace all endian.h in uspace with a copy of the kernel's respective byteorder.h.  
2796 5909 d 19 h jermar /trunk/uspace/srv/fs/fat/ Convert FAT on-disk metadata from little-endian to native representation.  
2793 5909 d 20 h jermar /trunk/uspace/srv/fs/fat/ First untested bits of FAT lookup support.  
2792 5909 d 20 h jermar /trunk/uspace/ libfs' node_get() operation does not need the file system handle.  
2791 5912 d 18 h jermar /trunk/uspace/ Make libfs_lookup() more generic.  
2789 5915 d 7 h jermar /trunk/uspace/srv/fs/fat/ Fix FAT boot sector definition and introduce the FAT in-core node type.  
2788 5915 d 8 h jermar /trunk/uspace/ Return EBUSY if trying to mount something over an already mounted root FS.
(Contributed by Tim Post)		  
2770 5931 d 20 h jermar /trunk/uspace/ Introduce fs_handle_t, dev_handle_t and fs_index_t.  
2769 5932 d 18 h jermar /trunk/uspace/srv/vfs/ VFS index needs to be treated as uint64_t.  
2768 5932 d 20 h jermar /trunk/uspace/srv/vfs/ Fibril serialization is required when two file systems register contemporarily.  
2766 5933 d 20 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 5933 d 23 h jermar /trunk/uspace/ Support for rename().  
2760 5936 d 18 h jermar /trunk/uspace/ Support for multiple TMPFS node names.  
2758 5937 d 18 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 5937 d 19 h jermar /trunk/uspace/srv/fs/tmpfs/ Set the TMPFS root node's link count to 1.  
2756 5937 d 20 h jermar /trunk/uspace/srv/fs/tmpfs/ Introduce real link counts for TMPFS.  
2753 5940 d 19 h jermar /trunk/uspace/ Move canonify() to libc so that it can be used also on the libc side.  
2752 5941 d 1 h jermar /trunk/uspace/srv/vfs/ Make VFS canonify path names on lookup.  
2751 5941 d 23 h jermar /trunk/uspace/ Add canonify() for file system path canonization.
Not yet used by VFS.		  
2749 5943 d 18 h jermar /trunk/uspace/srv/vfs/ contents_rwlock should not be acquired as a futex but rather as a rwlock.  
2748 5943 d 19 h jermar /trunk/uspace/srv/vfs/ Support for O_TRUNC.  
2747 5944 d 17 h jermar /trunk/uspace/ Move the core lookup logic from TMPFS to libfs.  
2742 5946 d 18 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 5952 d 18 h jermar /trunk/uspace/srv/vfs/ Initialize the VFS node properly.  
2739 5952 d 18 h jermar /trunk/uspace/srv/fs/tmpfs/ Remove duplicate initialization.  
2736 5954 d 20 h jermar /trunk/uspace/srv/fs/tmpfs/ Unlink a TMPFS node more thoroughly.  
2735 5955 d 0 h jermar /trunk/uspace/ Support for rmdir(), unlink() and the respective VFS operations.  
2734 5955 d 1 h jermar /trunk/uspace/ Support for close().  
2733 5955 d 2 h jermar /trunk/uspace/ Add TMPFS support for destroying leaf links in the file system namespace.  
2732 5955 d 2 h jermar /trunk/uspace/srv/fs/tmpfs/ When freeing up a TMPFS node, it should also be removed from the dentries hash table.  
2731 5955 d 3 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 5956 d 5 h jermar /trunk/uspace/srv/ Introduce the notion of VFS node link counts.  
2728 5960 d 18 h jermar /trunk/uspace/srv/fs/tmpfs/ Descend vs. descent.  
2711 5975 d 21 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 5975 d 21 h jermar /trunk/uspace/ VFS_WRITE and tmpfs_write fixes.  
2709 5975 d 23 h jermar /trunk/uspace/srv/vfs/ VFS_OPEN and VFS_WRITE now understand O_APPEND.
