Hello Alan
quoted
+ spin_unlock_irqrestore(&port->lock, flags);Looks good apart from this bit.. The copy needs to go to a temporary before the lock is taken otherwise we may sleep on a pagefault with irqs off Alan
Good catch I will fix it as you suggest. I will give a give a couple of days for comments about the serie "[PATCH 00/12] Handle TIOC[GS]RS485 iocts on serial_core" Then I will resend the series including this patch (of course, fixed) Thanks! -- Ricardo Ribalda
