|
|
* might not be TRUE but since the following two are just pointer copies, it is not considered a big overhead.
|
|
* this approach ensures that the jnl_put_jrt_pini gets the appropriate prc_vec for writing into the
|
|
* journal record in case JNL_ENABLED turns out to be TRUE in t_end time.
|
|
* note that the value of JNL_ALLOWED(cs_addrs) cannot be changed on the fly without obtaining standalone access
