## Summary This change fixes a divide-by-zero in stat() caused by overflow of st_blksize when a filesystem reports a block size larger than can be represented by blksize_t. As reported in #19432, this can occur with LittleFS configurations using large block sizes, where blksize_t is currently defined as int16_t. When the filesystem block size exceeds the range of int16_t, st_blksize is truncated to zero, causing an integer divide-by-zero when st_blocks is calculated. This patch widens blksize_t from int16_t to int32_t in include/sys/types.h and updates the corresponding nuttx_blksize_t definition in include/nuttx/fs/hostfs.h so the two definitions remain consistent.
