Bug Category:
Not for Release Notes
Release Note Summary:
Some MemorySanitizer instrumentation was added to aio_linux::getevent_thread_routine().
Sprint:
Sprint 7 (07.04.2025), Sprint 8 (21.04.2025), Sprint 9 (05.05.2025)

Description

So far, as per ~~MDEV-20377~~, we got MemorySanitizer to work only for the traditional synchronous file I/O.

Ideally, we should deviate from the default build options as little as possible. It turns out that with a few minor tweaks, the libaio code path can be made MSAN clean. For liburing, some additional changes to /usr/include/liburing/*.h seem to be necessary.
