From c11faf32599fee59f33896c8d59f9b3c17ca76fc Mon Sep 17 00:00:00 2001 From: Chengguang Xu Date: Wed, 24 Jun 2020 18:20:11 +0800 Subject: [PATCH] ovl: fix incorrect extent info in metacopy case In metacopy case, we should use ovl_inode_realdata() instead of ovl_inode_real() to get real inode which has data, so that we can get correct information of extentes in ->fiemap operation.
