wangchdo opened a new pull request, #17272:
URL: https://github.com/apache/nuttx/pull/17272
## Summary
The `need_switch` flag was not initialized in `event_post()`. Since it is
a local variable, it could contain a random non-zero value, leading to
incorrect behavior.
In addition, this patch also fixes an issue where the event clearing
operation in `event_post()` may not be performed correctly.
**The root cause of this issue is that during the restructuring of the
commit log for #17244 based on @jerpelea’s feedback, I inadvertently used an
outdated implementation of event_post from my local history and failed to
re-run the tests afterward.
I’ll take this as a valuable lesson — from now on, whenever I amend a
commit, I’ll make sure to re-run the tests to ensure no new issues are
introduced.**
## Impact
Fix an issue in the event_post implementation. This change has no impact on
other NuttX functions.
