Subject: [PATCH 06/26] xfs: use correct jiffies comparison function in xchk_maybe_relax
Date: Tue, 22 Sep 2026 13:02:01 +0200 [thread overview]
Message-ID: <20260922110221.1431-6-hackerowskiy@gmail.com> (raw)
In-Reply-To: <20260922110221.1431-1-hackerowskiy@gmail.com>
From: "Darrick J. Wong" <djwong@kernel.org>
LOLLM points out that we're supposed to use time_after_eq, not a raw >=
operation here, or else jiffies wraps can go unnoticed. Fix this.
Cc: stable@vger.kernel.org # v6.10
Fixes: 271557de7cbfde ("xfs: reduce the rate of cond_resched calls inside scrub")
