3665 5868 d 7 h rimsky /branches/sparc/ Merged latest trunk changes into the sparc brach.  
3593 5883 d 8 h rimsky /branches/sparc/ Merged latest trunk changes into sparc branch.  
3397 5949 d 17 h rimsky /branches/sparc/ Merged recent changes from trunk into the Sparc branch.  
3343 5973 d 14 h decky /branches/sparc/ add sparc branch  
3109 6047 d 15 h jermar /trunk/uspace/srv/ Split the 'mount another filesystem here' and 'you are being mounted and the
device is this' mount semantics. Add VFS_MOUNTED VFS operation that corresponds
to the latter and reserve VFS_MOUNT only for the former. Because of this
change, the VFS server does not maintain the mr_node VFS node for the name space
root anymore and the VFS_LOOKUP operation is now not meant to be used on
unmounted file system, not even for looking up the root node of unmounted file
systems. In the light of these changes, TMPFS is now initialized from
tmpfs_mounted() function.
 
3103 6048 d 8 h jermar /trunk/uspace/srv/fs/tmpfs/ Evict the code which loads the TMPFS file system from a file system dump to a
dedicated source file.
 
3091 6050 d 11 h jermar /trunk/uspace/srv/fs/tmpfs/ Return value argument to ipc_call_sync_X_Y() may not be int or it will
break on 64-machines that are sensitive to unaligned memory accesses.
Moreover, overcasting int * to sysarg_t * is not a good idea either
even if the int is by chance aligned on a 64-bit boundary as some
unknown memory will get overwritten during the assignment. Change the
type of the retval argument to ipcarg_t.
 
3087 6050 d 15 h decky /trunk/uspace/srv/fs/tmpfs/ initialize tmpfs from RAM disk  
2958 6066 d 9 h jermar /trunk/uspace/srv/ Make VFS_MOUNT call even when mounting the root file system.  
2863 6094 d 19 h jermar /trunk/uspace/ Revert libfs node_get() API to a model without the parent node pointer
argument.
 
2858 6100 d 3 h jermar /trunk/uspace/ libfs destroy operation should rather return an error code instead of a truth
value.
 
2857 6100 d 4 h jermar /trunk/uspace/ Add stubs for unimplemented FAT libfs operations.  
2852 6101 d 1 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.
 
2844 6102 d 8 h jermar /trunk/uspace/ Add fat_root_get() and fat_plb_get_char().  
2831 6105 d 1 h jermar /trunk/uspace/ Commit progress on the FAT file system server implementation.  
2792 6112 d 11 h jermar /trunk/uspace/ libfs' node_get() operation does not need the file system handle.  
2791 6115 d 8 h jermar /trunk/uspace/ Make libfs_lookup() more generic.  
2770 6134 d 10 h jermar /trunk/uspace/ Introduce fs_handle_t, dev_handle_t and fs_index_t.  
2763 6136 d 13 h jermar /trunk/uspace/ Support for rename().  
2760 6139 d 8 h jermar /trunk/uspace/ Support for multiple TMPFS node names.  
2758 6140 d 8 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 6140 d 10 h jermar /trunk/uspace/srv/fs/tmpfs/ Set the TMPFS root node's link count to 1.  
2756 6140 d 11 h jermar /trunk/uspace/srv/fs/tmpfs/ Introduce real link counts for TMPFS.  
2747 6147 d 8 h jermar /trunk/uspace/ Move the core lookup logic from TMPFS to libfs.  
2742 6149 d 8 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 6155 d 9 h jermar /trunk/uspace/srv/fs/tmpfs/ Remove duplicate initialization.  
2736 6157 d 10 h jermar /trunk/uspace/srv/fs/tmpfs/ Unlink a TMPFS node more thoroughly.  
2735 6157 d 14 h jermar /trunk/uspace/ Support for rmdir(), unlink() and the respective VFS operations.  
2733 6157 d 16 h jermar /trunk/uspace/ Add TMPFS support for destroying leaf links in the file system namespace.  
2732 6157 d 17 h jermar /trunk/uspace/srv/fs/tmpfs/ When freeing up a TMPFS node, it should also be removed from the dentries hash table.  
2731 6157 d 17 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 6158 d 19 h jermar /trunk/uspace/srv/ Introduce the notion of VFS node link counts.  
2728 6163 d 9 h jermar /trunk/uspace/srv/fs/tmpfs/ Descend vs. descent.  
2711 6178 d 11 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 6178 d 12 h jermar /trunk/uspace/ VFS_WRITE and tmpfs_write fixes.  
2707 6178 d 16 h jermar /trunk/uspace/ Support for mkdir().  
2706 6178 d 20 h jermar /trunk/uspace/srv/fs/tmpfs/ Move handling of the miss on excessive components out of the main loop in
tmpfs_lookup.
 
2705 6179 d 8 h jermar /trunk/uspace/ More elegant, flexible and complete version of tmpfs_lookup.  
2700 6186 d 17 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 6187 d 7 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.
