Dear Xiao, Thank you for your patch. Am 27.09.23 um 04:52 schrieb Xiao Ni:
With gcc version 13.2.1 20230918 (Red Hat 13.2.1-3) (GCC), it reports error: super-ddf.c:1988:58: error: array subscript -1 is below array bounds of ‘struct phys_disk_entry[0]’ [-Werror=array-bounds=]
I wouldn’t wrap pasted lines.
The subscrit is defined as int type. And it can be smaller than 0.
subscript?
To avoid this error, add -Wno-array-bounds flag in Makefile.
Wouldn’t it be better to fix the error and not work around it by disabling the warning?
Kind regards, Paul
