u-boot.git/fs/ext4/ext4_journal.h, branch master Unnamed repository; edit this file 'description' to name the repository. fs: ext4fs: add CONFIG_EXT4_MAX_JOURNAL_ENTRIES to Kconfig 2025-09-10T16:39:09+00:00 Tony Dinh mibodhi@gmail.com 2025-08-26T19:45:37+00:00 8c599da5060c2bb4c085a7d92794c8134f61ef25 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.

ext4: add support for filesystems without JOURNAL 2019-07-18T15:31:24+00:00 Marek Szyprowski m.szyprowski@samsung.com 2019-06-21T13:35:35+00:00 bd8fbd8a13b8a696aed312753f46432b19b61fd6 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 <m.szyprowski@samsung.com> Reviewed-by: Lukasz Majewski <lukma@denx.de>

SPDX: Convert all of our single license tags to Linux Kernel style 2018-05-07T13:34:12+00:00 Tom Rini trini@konsulko.com 2018-05-06T21:58:06+00:00 83d290c56fab2d38cd1ab4c4cc7099559c1d5046 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 <trini@konsulko.com>

ext4: fix endianess problems in ext4 write support 2016-09-23T13:02:04+00:00 Michael Walle michael@walle.cc 2016-09-01T09:21:40+00:00 58a9ecbaf4a2e2754509f52862a8a039b73b3744 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 <michael@walle.cc>
