Date: Mon, 21 Nov 2022 12:21:33 +0100 From: Alexander Potapenko <glider@...gle.com> To: glider@...gle.com Cc: linux-kernel@...r.kernel.org, akpm@...ux-foundation.org, tytso@....edu, adilger.kernel@...ger.ca, jaegeuk@...nel.org, chao@...nel.org, linux-fsdevel@...r.kernel.org, linux-ext4@...r.kernel.org, linux-f2fs-devel@...ts.sourceforge.net, Eric Biggers <ebiggers@...nel.org> Subject: [PATCH 4/5] fs: hfs: initialize fsdata in hfs_file_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.
