alias  value is busybox
  			
    kfree(alias);	//-----NOTE here ,after free alias, now the memory
hold alias is    `q@sbox


return form yaffs_follow_link ,back to VFS ,and finally goto yaffs_lookup:

in  yaffs_lookup:
	
	T(YAFFS_TRACE_OS,					
	  ( "yaffs_lookup for %d:%s\n",	
	   yaffs_InodeToObject(dir)->objectId, dentry->d_name.name));


	} else {
		T(YAFFS_TRACE_OS, ( "yaffs_lookup not found\n"));

	}

	//------NOTE HERE dentry->d_name.name is `q@sbox ,so we canot get the
real yaffs object(which should be busybox)




I think this is a problem of yaffs_follw_link,  is there somebody else
get the same result?
Charles  can you give some tip?
