commit 371c917b0b450d1944bf0ea18afdfc158af08f2e Author: John Baldwin <[email protected]> AuthorDate: 2022-04-06 23:45:27 +0000 Commit: John Baldwin <[email protected]> CommitDate: 2022-04-06 23:45:27 +0000 unlink_nhgrp: Remove write-only variable. Possibly one could assert that ret should always be 0 here (that is, that there was always an index found in the bitmask). That should be true since a bitmask index is allocated before the nhgrp is inserted in the ctl->gr_head list in link_nhgrp. --- sys/net/route/nhgrp.c | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) diff --git a/sys/net/route/nhgrp.c b/sys/net/route/nhgrp.c index 07abdf480101..32bcb56460a1 100644 --- a/sys/net/route/nhgrp.c +++ b/sys/net/route/nhgrp.c @@ -183,7 +183,7 @@ struct nhgrp_priv * unlink_nhgrp(struct nh_control *ctl, struct nhgrp_priv *key) { struct nhgrp_priv *nhg_priv_ret; - int ret, idx; + int idx; NHOPS_WLOCK(ctl); @@ -196,7 +196,7 @@ unlink_nhgrp(struct nh_control *ctl, struct nhgrp_priv *key) } idx = nhg_priv_ret->nhg_idx; - ret = bitmask_free_idx(&ctl->nh_idx_head, idx); + bitmask_free_idx(&ctl->nh_idx_head, idx); nhg_priv_ret->nhg_idx = 0; nhg_priv_ret->nh_control = NULL;
