This reduces the no. of syscalls on Linux systems from 2, accept(2) and fcntl(2) for setting O_NONBLOCK, to a single accept4(2). On NetBSD, we have paccept(2) that does the same, if we leave signal masking aside. Added sys_accept which accepts an extra flags argument than accept(2). This would opportunistically use accept4/paccept as available. It would fallback to accept(2) and fcntl(2) otherwise. While at this, the patch sets FD_CLOEXEC flag on the accepted socket fd.

Testing
GlusterFS source contains some functional tests under tests/ directory. All
these tests are run against every patch submitted for review. If you want your
patch to be tested, please add a .t test file as part of your patch submission.
You can also submit a patch to only add a .t file for the test case you are
aware of.
To run these tests, on your test-machine, just run ./run-tests.sh. Don't run
this on a machine where you have 'production' glusterfs is running, as it would
blindly kill all gluster processes in each runs.
If you are sending a patch, and want to validate one or few specific tests, then run a single test by running the below command.
bash# /bin/bash ${path_to_gluster}/tests/basic/rpc-coverage.t
You can also use prove tool if available in your machine, as follows.
bash# prove -vmfe '/bin/bash' ${path_to_gluster}/tests/basic/rpc-coverage.t
