[PATCH 09/12] lustre: Replace CURRENT_TIME macro
CURRENT_TIME macro is not y2038 safe on 32 bit systems.
The patch replaces all the uses of CURRENT_TIME by
current_time() for filesystem times, and ktime_get_*
functions for others.
struct timespec is also not y2038 safe.
Retain timespec for timestamp representation here as lustre
uses it internally everywhere.
These references will be changed to use struct timespec64
in a separate patch.
This is also in preparation for the patch that transitions
vfs timestamps to use 64 bit time and hence make them
y2038 safe. current_time() is also planned to be transitioned
to y2038 safe behavior along with this change.
CURRENT_TIME macro will be deleted before merging the
aforementioned change.
