H A D | resize.c | aec51758 Sun Aug 06 00:18:31 CDT 2017 Jerry Lee <jerrylee@qnap.com> ext4: fix overflow caused by missing cast in ext4_resize_fs()
On a 32-bit platform, the value of n_blcoks_count may be wrong during the file system is resized to size larger than 2^32 blocks. This may caused the superblock being corrupted with zero blocks count.
