------------------------------------------------------ From: Easwar Hariharan eahariha@linux.microsoft.com Subject: jiffies: cast to unsigned long for secs_to_jiffies() conversion Date: Thu, 30 Jan 2025 19:26:58 +0000
While converting users of msecs_to_jiffies(), lkp reported that some range checks would always be true because of the mismatch between the implied int value of secs_to_jiffies() vs the unsigned long return value of the msecs_to_jiffies() calls it was replacing. Fix this by casting secs_to_jiffies() values as unsigned long.
