Subject: [PATCH v4 1/2] s390: kernel: Convert timeouts to use secs_to_jiffies()
Date: Tue, 17 Dec 2024 23:09:58 +0000	[thread overview]
Message-ID: <20241217231000.228677-2-eahariha@linux.microsoft.com> (raw)
In-Reply-To: <20241217231000.228677-1-eahariha@linux.microsoft.com>

Commit b35108a51cf7 ("jiffies: Define secs_to_jiffies()") introduced
secs_to_jiffies(). As the values here are a multiple of 1000, use
secs_to_jiffies() instead of msecs_to_jiffies to avoid the multiplication.

This is converted using scripts/coccinelle/misc/secs_to_jiffies.cocci with
the following Coccinelle rules:

@@ constant C; @@

- msecs_to_jiffies(C * 1000)
+ secs_to_jiffies(C)

@@ constant C; @@

- msecs_to_jiffies(C * MSEC_PER_SEC)
+ secs_to_jiffies(C)

While here, manually convert the one other remaining instance as
requested.
