Subject: fuse2fs: don't truncate when creating a new file
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=e3a1437758398e8adcd141aabb7c572af8ef356a;p=thirdparty%2Fe2fsprogs.git

fuse2fs: don't truncate when creating a new file

New files can't have contents, so there's no need to truncate them,
which then messes with ctime/mtime.
