Subject: [PATCH 4.1 94/95] staging/lustre: use jiffies for lp_last_query times

4.1-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Arnd Bergmann <arnd@...db.de>

commit 9f088dba3cc267ea11ec0da318cd0175575b5f9b upstream.

The recently introduced lnet_peer_set_alive() function uses
get_seconds() to read the current time into a shared variable,
but all other uses of that variable compare it to jiffies values.

This changes the current use to jiffies as well for consistency.
