From c92737ceecaf24643cc58182afdf9b13074cfb0d Mon Sep 17 00:00:00 2001 From: Jaegeuk Kim Date: Tue, 7 Jun 2016 14:34:22 -0700 Subject: [PATCH] f2fs: fix deadlock in add_link failure mkdir sync_dirty_inode - init_inode_metadata - lock_page(node) - make_empty_dir - filemap_fdatawrite() - do_writepages - lock_page(data) - write_page(data) - lock_page(node) - f2fs_init_acl - error - truncate_inode_pages - lock_page(data) So, we don't need to truncate data pages in this error case, which will be done by f2fs_evict_inode.
