Subject: [PATCH] mm/buffer.c: remove the macro check in check_irqs_on()
Message-ID: <20201223063002.GA1526597@ubuntu-A520I-AC>
MIME-Version: 1.0
Content-Type: text/plain; charset=us-ascii
Content-Disposition: inline
Precedence: bulk

The macro irqs_disabled is always defined in include/linux/irqflags.h,
so we don't need the macro check.
