Hello,
Are there any pitfalls in using critical code locked through spinlocks,
inside a pair of lock_kernel()/unlock_kernel() calls on an SPM machine ?
I'm not familiar with SMP machines, hence the question.
Say we have the following code: is it safe, or should I use the classical
save_flags(), cli(), restore_flags() stuff ?
/* --------- */
lock_kernel();
spin_lock_irqsave(&lock, flags);
/* critical section ... */
spin_unlock_irqrestore(&lock, flags);
unlock_kernel();
/* --------- */
Please Cc your replies to my email address.
Thanks in advance,
