[PATCH 1/2] Reset the ret value when ignore an error from du_add_file()

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Goffredo Baroncelli <kreijack@xxxxxxxxx>

In du_walk_dir(), when du_add_file() returns an error it is
usually ignored. However if the error is returned querying
the last item, the error is returned to the caller.
