Subject: [PATCH v3 15/24] drivers: staging: lustre: Replace CURRENT_TIME with current_time()
CURRENT_TIME macro is not appropriate for filesystems as it
doesn't use the right granularity for filesystem timestamps.
Use current_time() instead.
This is also in preparation for the patch that transitions
vfs timestamps to use 64 bit time and hence make them
y2038 safe. As part of the effort current_time() will be
extended to do range checks. Hence, it is necessary for all
file system timestamps to use current_time().
Also change format string for prints so that these are valid
when vfs is transitioned to use 64 bit timestamps.
