   4 Subject: staging/lustre: use jiffies for lp_last_query times
   5

   8 commit 9f088dba3cc267ea11ec0da318cd0175575b5f9b upstream.
   9
  10 The recently introduced lnet_peer_set_alive() function uses
  11 get_seconds() to read the current time into a shared variable,
  12 but all other uses of that variable compare it to jiffies values.
  13
  14 This changes the current use to jiffies as well for consistency.
