2828 5973 d 13 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 5974 d 12 h jermar /trunk/uspace/srv/fs/fat/ Introduce and also use the foundation of block cache API in FAT's match
operation.
 
2798 5978 d 17 h jermar /trunk/uspace/ Replace all endian.h in uspace with a copy of the kernel's respective byteorder.h.  
2796 5979 d 17 h jermar /trunk/uspace/srv/fs/fat/ Convert FAT on-disk metadata from little-endian to native representation.  
2793 5979 d 18 h jermar /trunk/uspace/srv/fs/fat/ First untested bits of FAT lookup support.  
2792 5979 d 18 h jermar /trunk/uspace/ libfs' node_get() operation does not need the file system handle.  
2791 5982 d 15 h jermar /trunk/uspace/ Make libfs_lookup() more generic.  
2789 5985 d 5 h jermar /trunk/uspace/srv/fs/fat/ Fix FAT boot sector definition and introduce the FAT in-core node type.  
2770 6001 d 17 h jermar /trunk/uspace/ Introduce fs_handle_t, dev_handle_t and fs_index_t.  
2763 6003 d 20 h jermar /trunk/uspace/ Support for rename().  
2760 6006 d 15 h jermar /trunk/uspace/ Support for multiple TMPFS node names.  
2758 6007 d 15 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 6007 d 17 h jermar /trunk/uspace/srv/fs/tmpfs/ Set the TMPFS root node's link count to 1.  
2756 6007 d 18 h jermar /trunk/uspace/srv/fs/tmpfs/ Introduce real link counts for TMPFS.  
2747 6014 d 15 h jermar /trunk/uspace/ Move the core lookup logic from TMPFS to libfs.  
2742 6016 d 15 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 6022 d 16 h jermar /trunk/uspace/srv/fs/tmpfs/ Remove duplicate initialization.  
2736 6024 d 17 h jermar /trunk/uspace/srv/fs/tmpfs/ Unlink a TMPFS node more thoroughly.  
2735 6024 d 21 h jermar /trunk/uspace/ Support for rmdir(), unlink() and the respective VFS operations.  
2733 6024 d 23 h jermar /trunk/uspace/ Add TMPFS support for destroying leaf links in the file system namespace.  
2732 6025 d 0 h jermar /trunk/uspace/srv/fs/tmpfs/ When freeing up a TMPFS node, it should also be removed from the dentries hash table.  
2731 6025 d 0 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 6026 d 2 h jermar /trunk/uspace/srv/ Introduce the notion of VFS node link counts.  
2728 6030 d 16 h jermar /trunk/uspace/srv/fs/tmpfs/ Descend vs. descent.  
2711 6045 d 18 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 6045 d 19 h jermar /trunk/uspace/ VFS_WRITE and tmpfs_write fixes.  
2707 6045 d 23 h jermar /trunk/uspace/ Support for mkdir().  
2706 6046 d 3 h jermar /trunk/uspace/srv/fs/tmpfs/ Move handling of the miss on excessive components out of the main loop in
tmpfs_lookup.
 
2705 6046 d 15 h jermar /trunk/uspace/ More elegant, flexible and complete version of tmpfs_lookup.  
2700 6054 d 0 h jermar /trunk/uspace/ Introduce the notion of lflag (i.e. lookup flags) to support the ability to
limit the scope of VFS node types that can be opened by open() and opendir(). In
the future, lflag will also specify actions for VFS_LOOKUP handlers that will be
carried out in situations such as the VFS node is not found (e.g. implementation
of mkdir() and open() with O_CREAT in oflag).
 
2699 6054 d 14 h jermar /trunk/uspace/ Finish implementation of readdir(). Functions from this family are implemented
via using file descriptors for directories. For example, readdir() is
implemented as read() from an open directory. Of course, FS implementations
must understand that they are asked to read a directory and behave accordingly.
 
2693 6060 d 0 h jermar /trunk/uspace/ Add ftruncate() and support for VFS_TRUNCATE to VFS and TMPFS.  
2690 6064 d 16 h jermar /trunk/uspace/srv/ Make a distinction between VFS operations that are common to VFS and FS
implementations, operations that are VFS only and operations that are FS
implementations only.
 
2687 6064 d 17 h jermar /trunk/uspace/srv/ Management of the cached VFS node size.  
2686 6064 d 18 h jermar /trunk/uspace/srv/fs/tmpfs/ Previous commit was toxic. When emulating gaps, zero out the reallocated buffer, not the original one.  
2685 6064 d 18 h jermar /trunk/uspace/srv/fs/tmpfs/ TMPFS must handle file gaps.  
2678 6072 d 20 h jermar /trunk/uspace/ The IPC_M_SHARE_* and IPC_M_DATA_* calls pass through 3 stages. Rename the send,
receive and deliver wrappers to names ending with 'start', 'receive' and
'finalize', respectively. This should make it clearer for dummies.
 
2676 6073 d 3 h jermar /trunk/ Simplify the IPC_M_DATA_WRITE protocol. Do not pass the source address space
virtual address to the recipient. This feature was not used anyway. Now
IPC_M_DATA_WRITE and IPC_M_DATA_READ are feature-aligned.
 
2673 6073 d 16 h jermar /trunk/uspace/srv/fs/tmpfs/ Rename variable from 'size' to 'len'.  
2667 6078 d 13 h jermar /trunk/uspace/srv/fs/tmpfs/ The previous commit was not entirely sane.
Handle VFS_WRITE correctly when the file doesn't grow.
Handle it correctly also when the file grows.
