... LWN.net FAQ . ... Read-copy-update (RCU) is a mutual exclusion technique which can operate without locking most of the time. It can yield significant performance benefits when the data to be protected is accessed via a pointer, is read frequently, changed rarely, and references to the structure are not held while a kernel thread sleeps. The core idea behind RCU is that, when the data requires updating, a pointer to a new structure containing the new data can be stored immediately. ...

Finally, on a related note: We have changed the bias monitoring program for STIS in Cycle 8 in that we are now taking ~100 unbinned biases per week in CCDGAIN=1 (plus ~20 in CCDGAIN=4 and 14 in often-used binned modes in CCDGAIN=1) to enable one to create "straightforward" weekly unbinned CCDGAIN=1 bias reference files (thus eliminating the need to update the hot columns and thus the need to run the "weekbias" script). ...
