In wait_for_quiescent_state, the test for Q.S. is :
while (rcu_gp_ongoing(index->rcu_reader_qs_gp) &&
(*index->rcu_reader_qs_gp - urcu_gp_ctr < 0))
cpu_relax();
where :
static inline int rcu_gp_ongoing(long *value)
{
if (value == NULL)
return 0;
return LOAD_SHARED(*value) & 1;
}
Your proposal would work for the rcu_gp_ongoing test, as it only checks
for the parity. Given this test is enough to guarantee that we skip the
reader thread, then yes, it seems to work just fine.

urcu.c: declare noop urcu_init() function non-static
The RCU library is sometimes used in constructor context. In these cases,
because it is impossible to predict whether the liburcu constructor has already
been called, an explicit call to the urcu_init function must be made.
Declaring the noop version of the urcu_init() function as static breaks code
that calls urcu_init() explicitly when CONFIG_AVOID_SIGNALS is true. To prevent
this, this patch makes the declaration non-static.

Add SA_RESTART flag to signal handler
With this flag, the kernel restarts automatically some system calls
that were interrupted by the signal. Without this flag, these system
calls would fail with errno = EINTR.
Even with this flag, the kernel cannot restart some system calls, and
developers should verify whether these system calls failed with EINTR
and restart them manually in that case. For the list of system calls
that cannot be restarted automatically, see signal(7).
Because of this, we cannot completely eliminate the side-effects of
liburcu on the application, but I think we should try our best and
