Hi experts,

I found a file named lttng-statedump-impl.c in lttng-module is always
compiled failed. The file use some functions which were export from
kernel. But the v5.12 kernel unexport them by 'commit bc359d03c7ec
("block: add a disk_uevent helper")'.

The function are disk_part_iter_init()\disk_part_iter_next()
\disk_part_iter_exit()

Thanks,

Hi,

Can you have a look at this patch, it needs more testing :

https://review.lttng.org/c/lttng-modules/+/5050

Thanks, I have applied it to my project and it can perfectly solve the 
compile failure. Just a minor typo 'arounf' in src/wrapper/genhd.c

Regards,
Yanfei


Thanks,

Michael
