Subject: [patch 006/127] jiffies: add time comparison functions for 64 bit jiffies
Date: Fri, 07 Oct 2016 16:57:04 -0700 [thread overview]
Message-ID: <57f83650.ASU8c7u+q7VN9lgL%akpm@linux-foundation.org> (raw)
From: "Jason A. Donenfeld" <Jason@zx2c4.com>
Subject: jiffies: add time comparison functions for 64 bit jiffies
Though the time_before and time_after family of functions were nicely
extended to support jiffies64, so that the interface would be consistent,
it was forgotten to also extend the before/after jiffies functions to
support jiffies64. This commit brings the interface to parity between
jiffies and jiffies64, which is quite convenient.
