[PATCH 5.10 096/118] fuse: add file_modified() to fallocate

[Greg Kroah-Hartman <gregkh@xxxxxxxxxxxxxxxxxxx>]

From: Miklos Szeredi <mszeredi@xxxxxxxxxx>

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")
