From 6f974e8ce7b3f661910a49c7c2ba095631f341e9 Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Sun, 17 Jun 2012 18:40:54 -0400 Subject: target: move write_same to struct spc_ops Add spc_ops->execute_write_same() caller for ->execute_cmd() setup, and update IBLOCK backends to use it. (nab: add export of spc_get_write_same_sectors symbol) (roland: Carry forward: Fix range calculation in WRITE SAME emulation when num blocks == 0) Signed-off-by: Christoph Hellwig Signed-off-by: Nicholas Bellinger --- include/target/target_core_backend.h | 2 ++ 1 file changed, 2 insertions(+) (limited to 'include/target/target_core_backend.h') diff --git a/include/target/target_core_backend.h b/include/target/target_core_backend.h index 5797b1164c80..fbc6a1b8b99a 100644 --- a/include/target/target_core_backend.h +++ b/include/target/target_core_backend.h @@ -42,6 +42,7 @@ struct se_subsystem_api { struct spc_ops { int (*execute_rw)(struct se_cmd *cmd); int (*execute_sync_cache)(struct se_cmd *cmd); + int (*execute_write_same)(struct se_cmd *cmd); }; int transport_subsystem_register(struct se_subsystem_api *); @@ -55,6 +56,7 @@ void target_complete_cmd(struct se_cmd *, u8); int sbc_parse_cdb(struct se_cmd *cmd, struct spc_ops *ops); int spc_parse_cdb(struct se_cmd *cmd, unsigned int *size); +int spc_get_write_same_sectors(struct se_cmd *cmd); void transport_set_vpd_proto_id(struct t10_vpd *, unsigned char *); int transport_set_vpd_assoc(struct t10_vpd *, unsigned char *); -- cgit v1.2.3
