commit e388164ea385f04666c4633f5dc4f951fca71890 upstream.
The acceptable maximum value of lend parameter in filemap_write_and_wait_range() is LLONG_MAX rather than -1. And there is also some logic depending on LLONG_MAX check in write_cache_pages(). So let's pass LLONG_MAX to filemap_write_and_wait_range() in fuse_writeback_range() instead.
