From 7e437a39abaee1133ea4c30e75ef53eb47ca64b6 Mon Sep 17 00:00:00 2001 From: Jeremy Allison Date: Tue, 9 Apr 2013 10:29:47 -0700 Subject: Clean error paths in opendir and fd_opendir by only setting handle data on success. Pass extra struct dirsort_privates * to open_and_sort_dir() function to avoid it having to re-read the handle data.
