There are actually more macros in the code. Should all of them be redefined as functions? The original code looks like this: /* * macros for easy use */ #define rtsx_writel(chip, reg, value) \ iowrite32(value, (chip)->rtsx->remap_addr + reg) #define rtsx_readl(chip, reg) \ ioread32((chip)->rtsx->remap_addr + reg) #define rtsx_writew(chip, reg, value) \ iowrite16(value, (chip)->rtsx->remap_addr + reg) #define rtsx_readw(chip, reg) \ ioread16((chip)->rtsx->remap_addr + reg) #define rtsx_writeb(chip, reg, value) \ iowrite8(value, (chip)->rtsx->remap_addr + reg) #define rtsx_readb(chip, reg) \ ioread8((chip)->rtsx->remap_addr + reg) #define rtsx_read_config_byte(chip, where, val) \ pci_read_config_byte((chip)->rtsx->pci, where, val) #define rtsx_write_config_byte(chip, where, val) \ pci_write_config_byte((chip)->rtsx->pci, where, val) #define wait_timeout_x(task_state, msecs) \ do { \ set_current_state((task_state)); \ schedule_timeout((msecs) * HZ / 1000); \ } while (0) #define wait_timeout(msecs) wait_timeout_x(TASK_INTERRUPTIBLE, (msecs)) > > pci_read_config_byte((chip)->rtsx->pci, where, val) > > @@ -131,8 +131,8 @@ static inline struct rtsx_dev *host_to_rtsx(struct Scsi_Host *host) > > * The scsi_lock() and scsi_unlock() macros protect the sm_state and the > > * single queue element srb for write access > > */ > > -#define scsi_unlock(host) spin_unlock_irq(host->host_lock) > > -#define scsi_lock(host) spin_lock_irq(host->host_lock) > > +#define scsi_unlock(host) spin_unlock_irq((host)->host_lock) > > +#define scsi_lock(host) spin_lock_irq((host)->host_lock) > > For these ones, the name is too generic. probably the right thing is > to just get rid of them completely and call spin_lock/unlock_irq() > directly. I understand that there should be 2 different patches, one for the macro-to-function rewrites & one for replacing the scsi lock/unlock macros with direct spinlock calls. But, should these be in a patchset(they are vaguely related since the patches together would get rid of the checkpatch warnings)? I'm not sure.

Should all of > them be redefined as functions? The original code looks like this: You should make a static inline function if you can. That would require that the parameter types are the same at all call sites and that all of the arguments are used as values, not eg as the left side of an assignment (looks fine here). > > /* > * macros for easy use > */ > #define rtsx_writel(chip, reg, value) \ > iowrite32(value, (chip)->rtsx->remap_addr + reg) > #define rtsx_readl(chip, reg) \ > ioread32((chip)->rtsx->remap_addr + reg) > #define rtsx_writew(chip, reg, value) \ > iowrite16(value, (chip)->rtsx->remap_addr + reg) > #define rtsx_readw(chip, reg) \ > ioread16((chip)->rtsx->remap_addr + reg) > #define rtsx_writeb(chip, reg, value) \ > iowrite8(value, (chip)->rtsx->remap_addr + reg) > #define rtsx_readb(chip, reg) \ > ioread8((chip)->rtsx->remap_addr + reg) > > #define rtsx_read_config_byte(chip, where, val) \ > pci_read_config_byte((chip)->rtsx->pci, where, val) > > #define rtsx_write_config_byte(chip, where, val) \ > pci_write_config_byte((chip)->rtsx->pci, where, val) > > #define wait_timeout_x(task_state, msecs) \ > do { \ > set_current_state((task_state)); \ > schedule_timeout((msecs) * HZ / 1000); \ > } while (0) > #define wait_timeout(msecs) wait_timeout_x(TASK_INTERRUPTIBLE, (msecs)) > > > > pci_read_config_byte((chip)->rtsx->pci, where, val) > > > @@ -131,8 +131,8 @@ static inline struct rtsx_dev *host_to_rtsx(struct Scsi_Host *host) > > > * The scsi_lock() and scsi_unlock() macros protect the sm_state and the > > > * single queue element srb for write access > > > */ > > > -#define scsi_unlock(host) spin_unlock_irq(host->host_lock) > > > -#define scsi_lock(host) spin_lock_irq(host->host_lock) > > > +#define scsi_unlock(host) spin_unlock_irq((host)->host_lock) > > > +#define scsi_lock(host) spin_lock_irq((host)->host_lock) > > > > For these ones, the name is too generic. probably the right thing is > > to just get rid of them completely and call spin_lock/unlock_irq() > > directly. > > I understand that there should be 2 different patches, one for the > macro-to-function rewrites & one for replacing the scsi lock/unlock macros with > direct spinlock calls.

My last patch in the set didn't go through. THe error message is "multiple In-Reply-To headers. To reduce the amount of spam sent to Gmail, this message has been blocked." I used the --thread=shallow flag with git format-patch. Should I try resend the entire patch set again without the flag? Or is there any way to send the remaining patch by itself?
