2013-07-15Fix ext2/ext4 filesystem accesses beyond 2TiBFrederic Leroy
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>
2013-05-10fs/ext4: Support device block sizes != 512 bytesEgbert Eich
The 512 byte block size was hard coded in the ext4 file systems. Large harddisks today support bigger block sizes typically 4096 bytes. This patch removes this limitation. Signed-off-by: Egbert Eich <eich@suse.com>
2013-04-01Consolidate bool typeYork Sun
'bool' is defined in random places. This patch consolidates them into a single header file include/linux/types.h, using stdbool.h introduced in C99. All other #define, typedef and enum are removed. They are all consistent with true = 1, false = 0. Replace FALSE, False with false. Replace TRUE, True with true. Skip *.py, *.php, lib/* files. Signed-off-by: York Sun <yorksun@freescale.com>
