The impact seems to be quite high from the bird eye view. The check is intent: it is unnecessary to post semaphore more than once because there is one and only one thread is waiting for it: https://github.com/apache/incubator-nuttx/blob/master/fs/vfs/fs_poll.c#L423 you can see sem is a local variable defined at line 365. -- This is an automated message from the Apache Git Service.
