From 206e61be29624499af46546076e835da93e6bde5 Mon Sep 17 00:00:00 2001 From: Chao Yu Date: Wed, 12 Aug 2015 17:48:21 +0800 Subject: [PATCH] f2fs: avoid clear valid page In f2fs_delete_entry, if last dirent is remove from the dentry page, we will try to punch that page since it has no valid date in it. But truncate_hole which is used for punching could fail because of no memory or IO error, if that happened, we'd better skip clearing this valid dentry page.
