From: David Howells <dhowells@redhat.com>
Subject: shmem: apply a couple of filemap_splice_read() fixes to shmem_splice_read()
Date: Thu, 27 Jul 2023 17:10:16 +0100

Fix shmem_splice_read() to use the inode from in->f_mapping->host rather
than file_inode(in) and to skip the splice if it starts after s_maxbytes,
analogously with fixes to filemap_splice_read().
