From a9a6cb4f4693253349358f8163d826eb0cfecfbc Mon Sep 17 00:00:00 2001 From: Bhaktipriya Shridhar Date: Sat, 12 Mar 2016 01:31:20 +0530 Subject: [PATCH] staging: lustre: lnet: conrpc: Use list_for_each_entry_safe Doubly linked lists which are iterated using list_empty and list_entry macros have been replaced with list_for_each_entry_safe macro. This makes the iteration simpler and more readable. This patch replaces the while loop containing list_empty and list_entry with list_for_each_entry_safe. This was done with Coccinelle. @@ expression E1; identifier I1, I2; type T; iterator name list_for_each_entry_safe; @@ T *I1; + T *tmp; ... - while (list_empty(&E1) == 0) + list_for_each_entry_safe (I1, tmp, &E1, I2) { ...when != T *I1; - I1 = list_entry(E1.next, T, I2); ... } Signed-off-by: Bhaktipriya Shridhar Signed-off-by: Greg Kroah-Hartman --- drivers/staging/lustre/lnet/selftest/conrpc.c | 5 ++--- 1 file changed, 2 insertions(+), 3 deletions(-) diff --git a/drivers/staging/lustre/lnet/selftest/conrpc.c b/drivers/staging/lustre/lnet/selftest/conrpc.c index 32970ef777e3..5604fceb1a41 100644 --- a/drivers/staging/lustre/lnet/selftest/conrpc.c +++ b/drivers/staging/lustre/lnet/selftest/conrpc.c @@ -1335,6 +1335,7 @@ lstcon_rpc_cleanup_wait(void) { lstcon_rpc_trans_t *trans; lstcon_rpc_t *crpc; + lstcon_rpc_t *temp; struct list_head *pacer; struct list_head zlist; @@ -1374,9 +1375,7 @@ lstcon_rpc_cleanup_wait(void) spin_unlock(&console_session.ses_rpc_lock); - while (!list_empty(&zlist)) { - crpc = list_entry(zlist.next, lstcon_rpc_t, crp_link); - + list_for_each_entry_safe(crpc, temp, &zlist, crp_link) { list_del(&crpc->crp_link); LIBCFS_FREE(crpc, sizeof(lstcon_rpc_t)); } -- 2.39.5
