Subject: i8259.c spinlocks unnecessary
Date: Fri, 28 Jun 2002 15:29:29 -0600 [thread overview]
Message-ID: <20020628152929.K3851@host110.fsmlabs.com> (raw)
I looked through the 8259 code and I believe the spinlocks there are
unnecessary. The code is covered by a spinlock when called from irq.c.
I instrumented the code and after running quite some time my code review
matches what I've seen.
Anyone comment? Does someone want to remove them?
