With CONFIG_SYS_64BIT_LBA, lbaint_t gets defined as a 64-bit type, which is required to represent block numbers for storage devices that exceed 2TiB (the block size usually is 512B), e.g. recent hard drives We now use lbaint_t for partition offset to reflect the lbaint_t change, and access partitions beyond or crossing the 2.1TiB limit. This required changes to signature of ext4fs_devread(), and type of all variables relatives to block sector. ext2/ext4 fs uses logical block represented by a 32 bit value. Logical block is a multiple of device block sector. To avoid overflow problem when calling ext4fs_devread(), we need to cast the sector parameter. Signed-off-by: Frédéric Leroy <fredo@starox.org>
