[PATCH 1/6] scsi: bfa: bfa_svc: Use ktime_get_real_seconds()

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



32 bit systems using 'struct timeval' will break in the year 2038, so
we modify the code appropriately.

This patch removes the function bfa_get_log_time() which is only used
to get current time in seconds. bfa_get_log_time() is replaced with
ktime_get_real_seconds() which returns a 64 bit value.
