Author: delphij Date: Thu Feb 25 00:46:51 2010 New Revision: 204295 URL: http://svn.freebsd.org/changeset/base/204295 Log: MFC r202964: On FreeBSD, time_t is 64-bit for all platforms except i386 and powerpc, where the type is 32-bit. ZFS can handle 64-bit timestamp internally but zfs_setattr() would check if the time value can fit, we change the checking macros to match 64-bit timestamp if the platform supports it. This change has some downsides like, while you can import zfs on 32-bit platforms, the timestamp would overflow if they are out of the range. This fixes the Y2.038K issue on platforms using 64-bit timestamps.
