Thanks for looking into this. It can be complex with multi counts, multi
semaphores being held.
> The case is that task pend_reprios does not cover the source of
re-prioritisation (I mean if task holds 2 semaphores and first time it was
reprioritised due to holding semaphore 1 and second time due to semaphore 2) so
correct restoring to base priority is not possible.
Would you walk me through the fail with a little more detail?
We have tested our 10.1.0+ uses cases: single thread with multi count, multi
semaphores and the issues is resolved. There is an artificial case if the
lowest priority holder holds a second semaphore and never releases it.
I agree the design needs to be rethought out in upstream (with
https://github.com/apache/incubator-nuttx/pull/5171) I am happy to work
through that with you, but have not looked at how what
https://github.com/apache/incubator-nuttx/pull/5171 changed it.
