2025-09-10fs: ext4fs: add CONFIG_EXT4_MAX_JOURNAL_ENTRIES to KconfigTony Dinh
Add maximum ext4 journal entries to Kconfig. It is necessary since the number of journal entries is proportional to disk capacity. For example, an ext4 4TB HDD partition could require approximately 500 entries. Signed-off-by: Tony Dinh <[email protected]> Reviewed-by: Tom Rini <[email protected]>
2019-07-18ext4: add support for filesystems without JOURNALMarek Szyprowski
JOURNAL is optional for EXT4 (and EXT3) filesystems, so add support for skipping it. This fixes corrupting EXT4 volumes without JOURNAL after using uboot's 'ext4write' command. Signed-off-by: Marek Szyprowski <[email protected]> Reviewed-by: Lukasz Majewski <[email protected]>
2018-05-07SPDX: Convert all of our single license tags to Linux Kernel styleTom Rini
When U-Boot started using SPDX tags we were among the early adopters and there weren't a lot of other examples to borrow from. So we picked the area of the file that usually had a full license text and replaced it with an appropriate SPDX-License-Identifier: entry. Since then, the Linux Kernel has adopted SPDX tags and they place it as the very first line in a file (except where shebangs are used, then it's second line) and with slightly different comment styles than us. In part due to community overlap, in part due to better tag visibility and in part for other minor reasons, switch over to that style. This commit changes all instances where we have a single declared license in the tag as both the before and after are identical in tag contents. There's also a few places where I found we did not have a tag and have introduced one. Signed-off-by: Tom Rini <[email protected]>
2016-09-23ext4: fix endianess problems in ext4 write supportMichael Walle
All fields were accessed directly instead of using the proper byte swap functions. Thus, ext4 write support was only usable on little-endian architectures. Fix this. Signed-off-by: Michael Walle <[email protected]>
2016-09-23ext4: change structure fields to __le/__be typesMichael Walle
Change all the types of ext2/4 fields to little endian types and all the JBD fields to big endian types. Now we can use sparse (make C=1) to check for statements where we need byteswaps. Signed-off-by: Michael Walle <[email protected]>
