Subjectmainline build failure due to 281d0c962752 ("fortify: Add Clang support")
Hi All,

I have recently (since yesterday) started building the mainline kernel
with clang-14 and I am seeing a build failure with allmodconfig.

In file included from drivers/net/ethernet/huawei/hinic/hinic_devlink.c:15:
In file included from ./include/linux/netlink.h:7:
In file included from ./include/linux/skbuff.h:15:

In file included from ./include/linux/bitmap.h:11:
In file included from ./include/linux/string.h:253:
./include/linux/fortify-string.h:344:4: error: call to __write_overflow_field declared with 'warning' attribute: detected write beyond size of field (1st parameter); maybe use struct_group()? [-Werror,-Wattribute-warning]
__write_overflow_field(p_size_field, size);

After a bisect it pointed to 281d0c962752 ("fortify: Add Clang support").
Since it was introduced in v5.18, not sure if its already reported before.
