From f70cb33b9c270f4f1a7f28327e7d35dbf1a6fc40 Mon Sep 17 00:00:00 2001 From: Julia Lawall Date: Tue, 3 Aug 2010 23:34:16 +0200 Subject: [PATCH] fs/dlm: Drop unnecessary null test hlist_for_each_entry binds its first argument to a non-null value, and thus any null test on the value of that argument is superfluous. The semantic patch that makes this change is as follows: (http://coccinelle.lip6.fr/) // @@ iterator I; expression x,E,E1,E2; statement S,S1,S2; @@ I(x,...) { <... - (x != NULL) && E ...> } // Signed-off-by: Julia Lawall Signed-off-by: David Teigland --- fs/dlm/lowcomms.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/fs/dlm/lowcomms.c b/fs/dlm/lowcomms.c index c0d35c620526..37a34c2c622a 100644 --- a/fs/dlm/lowcomms.c +++ b/fs/dlm/lowcomms.c @@ -248,7 +248,7 @@ static struct connection *assoc2con(int assoc_id) for (i = 0 ; i < CONN_HASH_SIZE; i++) { hlist_for_each_entry(con, h, &connection_hash[i], list) { - if (con && con->sctp_assoc == assoc_id) { + if (con->sctp_assoc == assoc_id) { mutex_unlock(&connections_lock); return con; } -- 2.20.1
