Re: [PATCH] hrtimer: Fix the incorrect initialization of timer->is_hard

[cuiguoqi]

Hi tglx,
 
First of all, I'd like to thank you for your reply and for pointing out the email issue. 

As you've accurately noted, when PREEMPT_RT is disabled, it introduces a certain
degree of ambiguity for kernel developers. So far, no malfunctions have been
observed as a direct consequence of this.
 
This issue came to light during kernel development when using the is_hard flag, 
where the expected logic was not achieved.Naturally, we opted for the more reliable 
is_soft flag to address the situation.
 
Consequently, when PREEMPT_RT is disabled, there is a potential risk if developers
choose to use the is_hard flag. I firmly believe this risk should not be overlooked.

I concur with your analysis that one of these flags is redundant. In fact,
it might be possible to consolidate them based on the overall requirements. 
 
Thanks.
