From d19a7af73b5ecaac8168712d18be72b9db166768 Mon Sep 17 00:00:00 2001 From: "J. Bruce Fields" Date: Tue, 18 Jan 2022 17:00:51 -0500 Subject: lockd: fix failure to cleanup client locks In my testing, we're sometimes hitting the request->fl_flags & FL_EXISTS case in posix_lock_inode, presumably just by random luck since we're not actually initializing fl_flags here. This probably didn't matter before commit 7f024fcd5c97 ("Keep read and write fds with each nlm_file") since we wouldn't previously unlock unless we knew there were locks. But now it causes lockd to give up on removing more locks. We could just initialize fl_flags, but really it seems dubious to be calling vfs_lock_file with random values in some of the fields.
