[RFC 25/32] gfs2: convert to struct inode_time

[Arnd Bergmann]

gfs2 uses 64-bit integers for inode timestamps, which will work
basically forever, but the VFS uses struct timespec for timestamps,
which is only good until 2038 on 32-bit CPUs.

This gets us one small step closer to lifting the VFS limit by using
struct inode_time in gfs2.
