The upper limit that was initially setup for LOCKDEP_BITS configs is too high (24 bit shift), which causes the kernel image size to exceed KERNEL_IMAGE_SIZE (1024MB) limit. When LOCKDEP_BITS is set to 24, the kernel image size grows to 1562.19MB. Adjust LOCKDEP_BITS to 22, which results in a kernel image size of 888.19MB, keeping it under the KERNEL_IMAGE_SIZE limit while still maintaining adequate debug information capacity. This change prevents the linker error: ld: kernel image bigger than KERNEL_IMAGE_SIZE Fixes: e638072e6172 ("lockdep: Fix upper limit for LOCKDEP_*_BITS configs") Signed-off-by: Xiaomeng Zhang <zhangxiaomeng13@huawei.com> --- lib/Kconfig.debug | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-)
