Date: Tue, 2 Feb 2016 22:07:45 -0800 From: Deepa Dinamani <deepa.kernel@...il.com> To: linux-fsdevel@...r.kernel.org, y2038@...ts.linaro.org Cc: Arnd Bergmann <arnd@...db.de>, Dave Chinner <david@...morbit.com>, "Theodore Ts'o" <tytso@....edu>, linux-kernel@...r.kernel.org, Steve French <sfrench@...ba.org>, linux-cifs@...r.kernel.org, samba-technical@...ts.samba.org Subject: [PATCH 05/10] fs: cifs: Replace CURRENT_TIME by get_seconds This is in preparation for the series that transitions filesystem timestamps to use 64 bit time and hence make them y2038 safe. CURRENT_TIME macro will be deleted before merging the aforementioned series. Filesystems will use current_fs_time() instead of CURRENT_TIME. Use get_seconds() here as this is not filesystem time. Only the seconds portion of the timestamp is necessary for timezone calculation using server time. Assume that the difference between server and client times lie in the range INT_MIN..INT_MAX. This is valid because this is the difference between current times between server and client, and the largest timezone difference is in the range of one day.
