From 44b1b073eb36143ec65a918c0fbaa582f3ec2aa1 Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Tue, 10 Jun 2025 07:49:38 +0200 Subject: [PATCH 4326/5403] mm: stop passing a writeback_control structure to shmem_writeout shmem_writeout only needs the swap_iocb cookie and the split folio list. Pass those explicitly and remove the now unused list member from struct writeback_control.
