Subject: [PATCH 5.10 196/452] iomap: iomap_write_failed fix
From: Andreas Gruenbacher <agruenba@...hat.com>
[ Upstream commit b71450e2cc4b3c79f33c5bd276d152af9bd54f79 ]
The @lend parameter of truncate_pagecache_range() should be the offset
of the last byte of the hole, not the first byte beyond it.
Fixes: ae259a9c8593 ("fs: introduce iomap infrastructure")
