3352 5917 d 3 h jermar /trunk/uspace/srv/ Add reference to the mounted FS root.

This makes it possible to keep the FS root logically unlinked (i.e. lnkcnt == 0)
because it prevents VFS from attempting to destroy it during closedir().		  
3109 5994 d 7 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 5994 d 23 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 5997 d 3 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 5997 d 7 h decky /trunk/uspace/srv/fs/tmpfs/ initialize tmpfs from RAM disk  
2958 6013 d 0 h jermar /trunk/uspace/srv/ Make VFS_MOUNT call even when mounting the root file system.  
2863 6041 d 11 h jermar /trunk/uspace/ Revert libfs node_get() API to a model without the parent node pointer
argument.		  
2858 6046 d 19 h jermar /trunk/uspace/ libfs destroy operation should rather return an error code instead of a truth
value.		  
2857 6046 d 19 h jermar /trunk/uspace/ Add stubs for unimplemented FAT libfs operations.  
2852 6047 d 17 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

Add node_put() to libfs operations and instrument libfs_lookup() to use it at

2844 6049 d 0 h jermar /trunk/uspace/ Add fat_root_get() and fat_plb_get_char().  
2831 6051 d 17 h jermar /trunk/uspace/ Commit progress on the FAT file system server implementation.  
2792 6059 d 3 h jermar /trunk/uspace/ libfs' node_get() operation does not need the file system handle.  
2791 6062 d 0 h jermar /trunk/uspace/ Make libfs_lookup() more generic.  
2770 6081 d 2 h jermar /trunk/uspace/ Introduce fs_handle_t, dev_handle_t and fs_index_t.  
2763 6083 d 5 h jermar /trunk/uspace/ Support for rename().  
2760 6086 d 0 h jermar /trunk/uspace/ Support for multiple TMPFS node names.  
2758 6087 d 0 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 6087 d 2 h jermar /trunk/uspace/srv/fs/tmpfs/ Set the TMPFS root node's link count to 1.  
2756 6087 d 3 h jermar /trunk/uspace/srv/fs/tmpfs/ Introduce real link counts for TMPFS.
