[PATCH RFC 07/12] time: Rename rtc_time_to_tm() to rtc_time_to_tm_unsafe()
From: pang.xunlei
Date: Mon Oct 27 2014 - 01:47:41 EST
The kernel uses 32-bit signed value(time_t) for seconds since 1970-01-01:00:00:00, thus it
will overflow at 2038-01-19 03:14:08 on 32-bit systems. We call this "2038 safety" issue.
Currently, rtc_time_to_tm() deals with "unsigned long" which is 2038 unsafe on 32-bit systems.
As part of addressing 2038 saftey for in-kernel uses, this patch creates no creates no functional
change in existing users, renames rtc_time_to_tm() to rtc_time_to_tm_unsafe(), and changes all its
calling users correspondingly. The safe version of rtc_time_to_tm() will be added in the following patch.
