From e921cc4148d059e1812fd8b660d097068b26bbf2 Mon Sep 17 00:00:00 2001 From: Xiubo Li Date: Wed, 30 Aug 2023 13:24:01 +0800 Subject: [PATCH] mds: continue linking if targeti is temporarily located in stray dir If one inode has more than one hardlink and after the primary dentry is unlinked it will located the inode in the stray dir temporarily, which is pending reintegration. Just before the linkmerge/migrate is triggered a link request comes it will fail with -EXDEV. Just skip it and continue the linking.
