[PATCH 1/9] fs/ntfs3: Taking DOS names into account during link counting

by Konstantin Komarov

When counting and checking hard links in an ntfs file record, struct MFT_REC { struct NTFS_RECORD_HEADER rhdr; // 'FILE' __le16 seq; // 0x10: Sequence number for this record. >> __le16 hard_links; // 0x12: The number of hard links to record. __le16 attr_off; // 0x14: Offset to attributes. ... the ntfs3 driver ignored short names (DOS names), causing the link count to be reduced by 1 and messages to be output to dmesg. For Windows, such a situation is a minor error, meaning chkdsk does not report errors on such a volume, and in the case of using the /f switch, it silently corrects them, reporting that no errors were found. This does not affect the consistency of the file system. Nevertheless, the behavior in the ntfs3 driver is incorrect and changes the content of the file system. This patch should fix that. PS: most likely, there has been a confusion of concepts MFT_REC::hard_links and inode::__i_nlink.

[PATCH] kbuild: rust: remove unneeded `@rustc_cfg` to avoid ICE

by Miguel Ojeda

When KUnit tests are enabled, under very big kernel configurations (e.g. `allyesconfig`), we can trigger a `rustdoc` ICE [1]: RUSTDOC TK rust/kernel/lib.rs error: the compiler unexpectedly panicked. this is a bug. The reason is that this build step has a duplicated `@rustc_cfg` argument, which contains the kernel configuration, and thus a lot of arguments. The factor 2 happens to be enough to reach the ICE. Thus remove the unneeded `@rustc_cfg`. By doing so, we clean up the command and workaround the ICE. The ICE has been fixed in the upcoming Rust 1.79 [2].

I've attached a version that applies cleanly to 6.8, in case it is desirable. Cheers, Nathan

mlx5 driver fails to load in kernel 6.6.28

by Dragos Tatulea

Hi, Based on the issue reported here [0], commit 0553e753ea9e ("net/mlx5: E- switch, store eswitch pointer before registering devlink_param") is missing from kernel 6.6.x due to a missing tag. Could you please include it in 6.6.x and 6.8.x? [0] https://lore.kernel.org/netdev/20240422170428.32576-1-oxana@cloudflare.com/ Thanks, Dragos
