[PATCH openEuler-1.0-LTS] PCI/IOV: Improve performance of creating VFs concurrently
by Jialin Zhang 28 Apr '24

28 Apr '24

hulk inclusion category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/I9J08D -------------------------------- Previous commit 700a05bd8dba ("PCI/IOV: Add pci_sriov_numvfs_lock to support enable pci sriov concurrently") reduce performance of creating VFs belongs to different PFs. Fix it by checking whether a new bus will be created.
