Subject: [RESEND PATCH] qla2xxx: Remove use of 'struct timeval'
Date: Fri, 30 Oct 2015 02:15:26 -0700 [thread overview]
Message-ID: <20151030091526.GA4028@tina-laptop> (raw)
struct register_host_info stores a 64-bit UTC system time timestamp.
This patch removes the use of 'struct timeval' to obtain that timestamp
as its tv_sec value will overflow on 32-bit systems in year 2038 beyond.
The patch uses ktime_get_real_seconds() which returns a 64-bit seconds value.
