Without the test, 'epoll_notify' was called with a NULL
value for 'ectx->evs[i].data.ptr'. So it made a 'segmentation fault'.
It's very hard for me to give you more information because on
this computer I can't make 'gdb' and 'ltrace' works.
And the system doesn't make 'core dumps' even with 'ulimit -c'.
Attaching 'gdb' on a running 'glusterfsd' process kill it.
As I compiled 'gdb' and 'ltrace' myself, I am not sure about
the source of the problem.
And 'valgrind' doesn't work for ARM processor :-(
So I put many 'printf' in the sources to search the problem.
Sincerely yours.
