This series renames the perf_test_util to memstress. patch 1 renames the files perf_test_util.[ch] to memstress.[ch], and patch 2 replaces the perf_test_ prefix on symbols with memstress_. The reason for this rename, as with any rename, is to improve readability. perf_test_util is too generic and does not describe at all what the library does, other than being used for perf tests. I considered a lot of different names (naming is hard) and eventually settled on memstress for a few reasons: - "memstress" better describes the functionality proveded by this library, which is to run a VM that reads/writes to memory from all vCPUs in parallel (i.e. stressing VM memory). - "memstress" contains the same number of characters as "perf_test", making it a drop in replacement in symbols wihout changing line lengths. - The lack of underscore between "mem" and "stress" makes it clear "memstress" is a noun, avoiding confusion in function names. Looking to the future, I think "memstress" will remain a good name. Specifically there are some in-flight improvements that will make this library even more of a "memory stress tester": - A proposed series by yours truly [1] extends memstress/perf_test_util to support execute from memory, in addition to reading/writing. - Colton Lewis within Google is looking into adding support for more complex memory access patterns.
