From 3b7bf5933cada732783554edf0dc61283551c6cf Mon Sep 17 00:00:00 2001 From: Chuck Lever Date: Wed, 27 Jul 2022 14:40:59 -0400 Subject: [PATCH] NFSD: Refactor nfsd4_do_copy() Refactor: Now that nfsd4_do_copy() no longer calls the cleanup helpers, plumb the use of struct file pointers all the way down to _nfsd_copy_file_range().
