Re: [PATCH 4.19] scsi: sd: Fix 'sdkp' in sd_first_printk

This is defined in the 4.19 kernel:

#define sd_printk(prefix, sdsk, fmt, a...) \
(sdsk)->disk ? \
sdev_prefix_printk(prefix, (sdsk)->device, \
(sdsk)->disk->disk_name, fmt, ##a) : \
sdev_printk(prefix, (sdsk)->device, fmt, ##a)

#define sd_first_printk(prefix, sdsk, fmt, a...) \
do { \
if ((sdkp)->first_scan) \
sd_printk(prefix, sdsk, fmt, ##a); \
} while (0)



Most of the sdsk used in the macro definition has only one sdkp.


This is defined in the v6.0-rc7 kernel:

#define sd_printk(prefix, sdsk, fmt, a...) \
(sdsk)->disk ? \
sdev_prefix_printk(prefix, (sdsk)->device, \
(sdsk)->disk->disk_name, fmt, ##a) : \
sdev_printk(prefix, (sdsk)->device, fmt, ##a)

#define sd_first_printk(prefix, sdsk, fmt, a...) \
do { \
if ((sdsk)->first_scan) \
sd_printk(prefix, sdsk, fmt, ##a); \
} while (0)

Use sdsk in macro definition.


I did report an error when compiling sd. o in the 4.19 kernel. It was modified to say that no more errors were reported in sdsk. Can I continue the 6.0-rc7 writing method here.
