remove directory incorrectly tries to set delete on close on non-empty directories
Wrong return code was being returned on SMB3 rmdir of
non-empty directory.
For SMB3 (unlike for cifs), we attempt to delete a directory by
set of delete on close flag on the open. Windows clients set
this flag via a set info (SET_FILE_DISPOSITION to set this flag)
which properly checks if the directory is empty.
With this patch on smb3 mounts we correctly return
"DIRECTORY NOT EMPTY"
on attempts to remove a non-empty directory.
