mainline inclusion from mainline-v6.1-rc1 commit e07ee6fe21f47cfd72ae566395c67a80e7c66163 category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/I76JSK CVE: NA
Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?i...
--------------------------------
xfs_rename can update up to 5 inodes: src_dp, target_dp, src_ip, target_ip and wip. So we need to increase the inode reservation to match.
