[GitHub] [incubator-nuttx] zhaoxiu-zeng opened a new pull request #5120: signal: signal handler may cause task's state error
zhaoxiu-zeng opened a new pull request #5120:
URL: https://github.com/apache/incubator-nuttx/pull/5120
For example, task is blocked by nxsem_wait(sem1), use nxsem_wait(sem2)
in signal handler, and take sem2 successfully, after exit from signal
handler to task, nxsem_wait(sem1) returns OK, but the correct result
should be -EINTR.
