* kernel: fix f2fs on big endian machinesChristian Lamparter2018-12-291-0/+49
The WD MyBook Live SquashFS images didn't work anymore due to a upstream regression in f2fs commit: 0cfe75c5b01199 ("f2fs: enhance sanity_check_raw_super() to avoid potential overflows") that got backported to 4.14.86 and landed in 4.18. by Martin Blumenstingl: |Treat "block_count" from struct f2fs_super_block as 64-bit little endian |value in sanity_check_raw_super() because struct f2fs_super_block |declares "block_count" as "__le64". | |This fixes a bug where the superblock validation fails on big endian |devices with the following error: | F2FS-fs (sda1): Wrong segment_count / block_count (61439 > 0) | F2FS-fs (sda1): Can't find valid F2FS filesystem in 1th superblock | F2FS-fs (sda1): Wrong segment_count / block_count (61439 > 0) | F2FS-fs (sda1): Can't find valid F2FS filesystem in 2th superblock |As result of this the partition cannot be mounted. | |With this patch applied the superblock validation works fine and the |partition can be mounted again: | F2FS-fs (sda1): Mounted with checkpoint version = 7c84 | |My little endian x86-64 hardware was able to mount the partition without |this fix. |To confirm that mounting f2fs filesystems works on big endian machines |again I tested this on a 32-bit MIPS big endian (lantiq) device. Hopefully, this will do until Martin's patch moved through upstream to -stable. Signed-off-by: Christian Lamparter <chunkeey@gmail.com>
