Subject: fuse: add file_modified() to fallocate
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=0417f70b8588e03b16651897035bd99b0d144e93;p=linux.git

fuse: add file_modified() to fallocate

commit 4a6f278d4827b59ba26ceae0ff4529ee826aa258 upstream.

Add missing file_modified() call to fuse_file_fallocate().  Without this
fallocate on fuse failed to clear privileges.

Fixes: 05ba1f082300 ("fuse: add FALLOCATE operation")
