History
John Baldwin e89d5f43da Threads holding a read lock of a sleepable rm lock are not permitted 
to sleep.  The rmlock implementation enforces this by disabling
sleeping when a read lock is acquired. To simplify the implementation,
sleeping is disabled for most of the duration of rm_rlock.  However,
it doesn't need to be disabled until the lock is acquired.  If a
sleepable rm lock is contested, then rm_rlock may need to acquire the
backing sx lock.  This tripped the overly-broad assertion.  Fix by
relaxing the assertion around the call to sx_xlock().
