'volatile' pointers to access those structures, so that optimizing compilers will not decide to move the structure accesses outside of the spinlock-acquire-to-spinlock-release sequence. There are no known bugs in these uses at present, but based on bad experience with lwlock.c, it seems prudent to ensure that we protect these other uses too. Per pghackers discussion around 12-Dec. (Note: it should not be necessary to worry about structures protected by LWLocks, since the LWLock acquire and release operations are not inline macros.) |
