From bb6e0ebed7f7474e0e44cf6b778ee2fda759ddd6 Mon Sep 17 00:00:00 2001 From: Bhumika Goyal Date: Mon, 28 Nov 2016 14:57:42 +1100 Subject: [PATCH] fs: xfs: xfs_icreate_item: constify xfs_item_ops structure Declare the structure xfs_item_ops as const as it is only passed as an argument to the function xfs_log_item_init. As this argument is of type const struct xfs_item_ops *, so xfs_item_ops structures having this property can be declared as const.
