Subject: Spinlocks and interrupts
Date: Wed, 09 Nov 2011 14:07:31 -0700	[thread overview]
Message-ID: <4EBAEB93.3030008@gnukai.com> (raw)

When I readup on spinlocks, it seems like I need to choose between 
disabling interrupts and not. If a spinlock_t is never used during an 
interrupt, am I safe to leave interrupts enabled while I hold the lock? 
(Same question for read/write locks if it is different.)
