[PATCH] char/lp: convert to y2038 safe

by Bamvor Jian Zhang

The y2038 issue of printer exist in the time_t of timeval in ioctl LPSETTIME. This patch try to convert it to y2038 safe by the following steps: 1. Remove timeval from lp_set_timeout in order to support 32bit and 64bit time_t in the same function without the new definition of timeval64 or something else. 2. Handle both 32bit and 64bit time in the same LPSETTIMEOUT switch case in order to support y2038 safe and non-safe cases. 3. Merge compat of LPSETTIMEOUT into non-comapt one. I thought split these steps into three different patches. But I feel these changes are simple and direct.

[PATCH v2] block: sx8.c: Replace timeval with ktime_t

by shraddha.6596＠gmail.com

From: Shraddha Barke <shraddha.6596(a)gmail.com> 32-bit systems using 'struct timeval' will break in the year 2038, in order to avoid that replace the code with more appropriate types. This patch replaces the use of struct timeval and do_gettimeofday() with ktime_get_real_seconds() which returns a 64 bit seconds value. Real time is used since if monotonic time is used we would get duplicate timestamps after reboot as monotonic time starts from zero on every reboot.

[PATCH v2 0/4] fs: Add 64 bit time support

by Deepa Dinamani

The first two patches contain the basic framework for the 64 bit time migration for filesystems. The next two patches shows how the framework has been adapted to vfs layer and cifs filesystem. There might be some minor changes or additions required as I start adapting to other filesystems. The change to timestamp conversion functions(to and from unix format to others) and range checks will be part of a separate series. Changes since v1: * move SYSTEM_TIME macros to fs.h * add 64 bit version of CURRENT_TIME macros.
