On disk extents format: /* * this is extent on-disk structure * it's used at the bottom of the tree */ struct ext3_extent { __le32 ee_block; /* first logical block extent covers */ __le16 ee_len; /* number of blocks covered by extent */ __le16 ee_start_hi; /* high 16 bits of physical block */ __le32 ee_start; /* low 32 bigs of physical block */ };From a quick scan:
- There are several places which appear to be putting block numbers into an `int'.
This is fixed in [PATCH 4/9] 48bit support in extents, where we converted those "int" type block numbers to ext4_fsblk_t (which is typedefined as sector_t to support 48bit)
