| |
'0x7FDEADBEEF' will be truncated to 32-bit number under unicore32. Need append 'ULL' for it.
The related warning (with allmodconfig under unicore32):
CC [M] fs/ext4/extents_status.o fs/ext4/extents_status.c: In function ‘__es_remove_extent’: fs/ext4/extents_status.c:813: warning: integer constant is too large for ‘long’ type
