Building with gcc 4.9.2 on Ubuntu 15.04 I get the following build error:

libtool: link: gcc -g -Wall -fPIC -D_GNU_SOURCE -g -O2 -Werror -o llapi_fid_test llapi_fid_test.o ../../lustre/utils/liblustreapi.a

Makefile:1195: recipe for target 'sendfile_grouplock.o' failed

I'm guessing that the newer versions of gcc are more pedantic and catching this open + O_CREATE without mode flag issue.

Attached is a patch to fix this build issue.
