* [U-Boot] [PATCH] ext4: fix calculating inode blkcount for non-512 blocksize filesystems [not found] <CGME20190621133316eucas1p2dc0538511904be2f0efe8fceccb823bb@eucas1p2.samsung.com> @ 2019-06-21 13:32 ` Marek Szyprowski 2019-06-24 9:32 ` Lukasz Majewski 2019-07-18 23:56 ` Tom Rini 0 siblings, 2 replies; 3+ messages in thread From: Marek Szyprowski @ 2019-06-21 13:32 UTC (permalink / raw) To: u-boot The block count entry in the EXT4 filesystem disk structures uses standard 512-bytes units for most of the typical files. The only exception are HUGE files, which use the filesystem block size, but those are not supported by uboot's EXT4 implementation anyway. This patch fixes the EXT4 code to use proper unit count for inode block count. This fixes errors reported by fsck.ext4 on disks with non-standard (i.e. 4KiB, in case of new flash drives) PHYSICAL block size after using 'ext4write' uboot's command.
