Subject: dir.c: clean the entire struct in clear_exclude_list()
X-Git-Tag: v2.7.1~27^2
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=2653a8c6fa0466828061a3132421cf13a5d6d924;p=thirdparty%2Fgit.git

dir.c: clean the entire struct in clear_exclude_list()

Make sure "el" can be reuseable again. The problem was el->alloc is
not cleared and may cause segfaults next time because add_exclude()
thinks el->excludes (being NULL) has enough space. Just clear the
entire struct to be safe.
