From 1fffe1ce02917fe67e8902feb83493668076de7c Mon Sep 17 00:00:00 2001 From: Daeho Jeong Date: Tue, 9 Apr 2024 16:34:11 -0700 Subject: [PATCH] f2fs: write missing last sum blk of file pinning section BugLink: https://bugs.launchpad.net/bugs/2073603 commit b084403cfc3295b59a1b6bcc94efaf870fc3c2c9 upstream. While do not allocating a new section in advance for file pinning area, I missed that we should write the sum block for the last segment of a file pinning section.
