This fixes the following warning at sd_open function, which happens
because gcc isn't always perfect with determining whether a variable
is used uninitialized:
cc -c -DUSE_SIGNALFD -DUSE_TIMERFD -D_GNU_SOURCE -I. -g -O2
-fno-strict-aliasing -Wall -Wstrict-prototypes -fPIC DTGT_VERSION=\"\"
--DBSDIR=\"/lib/tgt/backing-store\" bs_sheepdog.c o bs_sheepdog.o
bs_sheepdog.c: In function 'sd_open':
bs_sheepdog.c:920: warning: 'saveptr' may be used uninitialized in
this function
