From 3d8e560de4a076b302cb0cc17e998aaace2b176a Mon Sep 17 00:00:00 2001 From: Jeff Layton Date: Fri, 16 Jan 2015 15:05:58 -0500 Subject: locks: consolidate NULL i_flctx checks in locks_remove_file We have each of the locks_remove_* variants doing this individually. Have the caller do it instead, and have locks_remove_flock and locks_remove_lease just assume that it's a valid pointer.
