[PATCH 31/37] staging/lustre: use 64-bit times for ptlrpc_sec

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

 



Here we use an unsigned long to store the timeout for gc,
which is probably safe until 2106, but this patch converts it
to use ktime_get_real_seconds() and time64_t for consistency.
