From 7ca76311fe6c397e9f332e5e6c79e3310d5ee98a Mon Sep 17 00:00:00 2001 From: Jeff Layton Date: Mon, 1 Sep 2014 19:04:48 -0400 Subject: [PATCH] locks: set fl_owner for leases to filp instead of current->files Like flock locks, leases are owned by the file description. Now that the i_have_this_lease check in __break_lease is gone, we don't actually use the fl_owner for leases for anything. So, it's now safe to set this more appropriately to the same value as the fl_file. While we're at it, fix up the comments over the fl_owner_t definition since they're rather out of date.
