From: Karsten Graul <kgraul@linux.ibm.com> mainline inclusion from mainline-v5.11-rc1 commit 8cf3f3e42374cc030b814ee2202eba14c5812d14 category: feature bugzilla: https://gitee.com/openeuler/kernel/issues/IC914B Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?i... -------------------------------- The helper smc_connect_abort() can be used by the listen processing functions, too. And rename this helper to smc_conn_abort() to make the purpose clearer. No functional change.
