From e388164ea385f04666c4633f5dc4f951fca71890 Mon Sep 17 00:00:00 2001 From: Xie Yongji Date: Mon, 22 Nov 2021 17:05:31 +0800 Subject: fuse: Pass correct lend value to filemap_write_and_wait_range() 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.
