Subject: [PATCH v3 2/2] drivers: hv: Convert open-coded timeouts to secs_to_jiffies()
Date: Wed, 30 Oct 2024 17:47:36 +0000	[thread overview]
Message-ID: <20241030-open-coded-timeouts-v3-2-9ba123facf88@linux.microsoft.com> (raw)
In-Reply-To: <20241030-open-coded-timeouts-v3-0-9ba123facf88@linux.microsoft.com>

We have several places where timeouts are open-coded as N (seconds) * HZ,
but best practice is to use the utility functions from jiffies.h. Convert
the timeouts to be compliant. This doesn't fix any bugs, it's a simple code
improvement.
