scsi: mptscsih: Mark expected switch fall-throughs

2019-04-04T03:45:59Z

In preparation to enabling -Wimplicit-fallthrough, mark switch cases where we are expecting to fall through. This patch fixes the following warnings: drivers/message/fusion/mptscsih.c: In function mptscsih_io_done : drivers/message/fusion/mptscsih.c:741:7: warning: this statement may fall through [-Wimplicit-fallthrough=] if ( ioc->bus_type == SAS ) { ^ drivers/message/fusion/mptscsih.c:790:3: note: here case MPI_IOCSTATUS_SCSI_TASK_TERMINATED: /* 0x0048 */ ^~~~ drivers/message/fusion/mptscsih.c:884:4: warning: this statement may fall through [-Wimplicit-fallthrough=] scsi_set_resid(sc, 0); ^~~~~~~~~~~~~~~~~~~~~ drivers/message/fusion/mptscsih.c:885:3: note: here case MPI_IOCSTATUS_SCSI_RECOVERED_ERROR: /* 0x0040 */ ^~~~ Warning level 3 was used: -Wimplicit-fallthrough=3 This patch is part of the ongoing efforts to enable -Wimplicit-fallthrough.

scsi: flip the default on use_clustering

2018-12-19T04:13:12Z

Most SCSI drivers want to enable "clustering", that is merging of segments so that they might span more than a single page. Remove the ENABLE_CLUSTERING define, and require drivers to explicitly set DISABLE_CLUSTERING to disable this feature. Signed-off-by: Christoph Hellwig Signed-off-by: Martin K. Petersen

scsi: message: fusion: Replace GFP_ATOMIC with GFP_KERNEL

2018-07-31T03:17:53Z

mpt_attach() and mptfc_probe() are never called in atomic context. They call kzalloc() and kcalloc() with GFP_ATOMIC, which is not necessary. GFP_ATOMIC can be replaced with GFP_KERNEL. This is found by a static analysis tool named DCNS written by myself. Signed-off-by: Jia-Ju Bai Signed-off-by: Martin K. Petersen
