Subject: [PATCH 3.18 26/50] mmc: mmc: fix switch timeout issue caused by jiffies precision
Date: Mon,  1 Apr 2019 19:03:09 +0200	[thread overview]
Message-ID: <20190401170044.200076740@linuxfoundation.org> (raw)
In-Reply-To: <20190401170041.257273804@linuxfoundation.org>

3.18-stable review patch.  If anyone has any objections, please let me know.

------------------

[ Upstream commit 987aa5f8059613bf85cbb6f64ffbd34f5cb7a9d1 ]

with CONFIG_HZ=100, the precision of jiffies is 10ms, and the
generic_cmd6_time of some card is also 10ms. then, may be current
time is only 5ms, but already timed out caused by jiffies precision.
