Subject: libmultipath: zero out lines in print.c
X-Git-Tag: 0.4.9~108
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=0ff6c45532fb4e289ceac882c69537efa3a6d53c;p=platform%2Fupstream%2Fmultipath-tools.git

libmultipath: zero out lines in print.c

static declaration of line within a function doesn't place them in
the bss segment, hence they are not zeroed automatically.
Gives funny effects occasionally.
