From eef034ac6690118c88f357b00e2b3239c9d8575d Mon Sep 17 00:00:00 2001 From: Alexander Potapenko Date: Tue, 10 Jan 2023 13:49:30 +0100 Subject: affs: initialize fsdata in affs_truncate() When aops->write_begin() does not initialize fsdata, KMSAN may report an error passing the latter to aops->write_end(). Fix this by unconditionally initializing fsdata.
