[Samba] exporting an FUSE base file system to windows

[doug]

Hi, 
 I still need help to try and figure this out.

When I do a directory listing on the windows SMB client my smbd server
in debug mode always seems to return:
 
[2007/11/13 15:00:05, 5] smbd/trans2.c:get_lanman2_dir_entry(1169)
  get_lanman2_dir_entry found srb_data/srb fname=srb
[2007/11/13 15:00:05, 10] smbd/trans2.c:get_lanman2_dir_entry(1310)
  get_lanman2_dir_entry: SMB_FIND_FILE_BOTH_DIRECTORY_INFO
[2007/11/13 15:00:05, 8] smbd/trans2.c:get_lanman2_dir_entry(1079)
  get_lanman2_dir_entry:readdir on dirptr 0x8d867d8 now at offset -1
[2007/11/13 15:00:05, 5] smbd/trans2.c:call_trans2findfirst(1798)
  call_trans2findfirst - (2) closing dptr_num 256
[2007/11/13 15:00:05, 4] smbd/dir.c:dptr_close_internal(238)
  closing dptr key 256

i.e. offset = -1 for my fuse mounted file system. 
(its also always last in the file list for some reason)
(and I changed the fuse mount point from my previous email) 
maybe those two things are correlated, or could the offset=-1 
be a pointer to some bug in my fuse based virtual filesystem?

thanks for any guidance

Doug
