This patch replaces rcu_assign_pointer(x, NULL) with RCU_INIT_POINTER(x, NULL) The rcu_assign_pointer() ensures that the initialization of a structure is carried out before storing a pointer to that structure. And in the case of the NULL pointer, there is no structure to initialize. So, rcu_assign_pointer(p, NULL) can be safely converted to RCU_INIT_POINTER(p, NULL) Signed-off-by: Monam Agarwal <monamagarwal123@xxxxxxxxx> --- drivers/scsi/libfc/fc_libfc.c | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) diff --git a/drivers/scsi/libfc/fc_libfc.c b/drivers/scsi/libfc/fc_libfc.c index 8d65a51a..c11a638 100644 --- a/drivers/scsi/libfc/fc_libfc.c +++ b/drivers/scsi/libfc/fc_libfc.c @@ -296,9 +296,9 @@ void fc_fc4_deregister_provider(enum fc_fh_type type, struct fc4_prov *prov) BUG_ON(type >= FC_FC4_PROV_SIZE); mutex_lock(&fc_prov_mutex); if (prov->recv) - rcu_assign_pointer(fc_passive_prov[type], NULL); + RCU_INIT_POINTER(fc_passive_prov[type], NULL); else - rcu_assign_pointer(fc_active_prov[type], NULL); + RCU_INIT_POINTER(fc_active_prov[type], NULL); mutex_unlock(&fc_prov_mutex); synchronize_rcu(); } -- 1.7.9.5 -- To unsubscribe from this list: send the line "unsubscribe linux-scsi" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
