f0883b9c39Eric Biggers <ebiggers@kernel.org> says: This is a cleaned-up implementation of moving the i_crypt_info and i_verity_info pointers out of 'struct inode' and into the fs-specific part of the inode, as proposed previously by Christian at https://lore.kernel.org/r/20250723-work-inode-fscrypt-v4-0-c8e11488a0e6@kernel.org/ The high-level concept is still the same: fs/crypto/ and fs/verity/ locate the pointer by adding an offset to the address of struct inode. The offset is retrieved from fscrypt_operations or fsverity_operations. I've cleaned up a lot of the details, including: - Grouped changes into patches differently - Rewrote commit messages and comments to be clearer - Adjusted code formatting to be consistent with existing code - Removed unneeded #ifdefs - Improved choice and location of VFS_WARN_ON_ONCE() statements - Added missing kerneldoc for ubifs_inode::i_crypt_info - Moved field initialization to init_once functions when they exist - Improved ceph offset calculation and removed unneeded static_asserts - fsverity_get_info() now checks IS_VERITY() instead of v_ops - fscrypt_put_encryption_info() no longer checks IS_ENCRYPTED(), since I no longer think it's actually correct there. - verity_data_blocks() now keeps doing a raw dereference - Dropped fscrypt_set_inode_info() - Renamed some functions - Do offset calculation using int, so we don't rely on unsigned overflow - And more. * patches from https://lore.kernel.org/20250810075706.172910-1-ebiggers@kernel.org: fsverity: check IS_VERITY() in fsverity_cleanup_inode() fs: remove inode::i_verity_info btrfs: move verity info pointer to fs-specific part of inode f2fs: move verity info pointer to fs-specific part of inode ext4: move verity info pointer to fs-specific part of inode fsverity: add support for info in fs-specific part of inode fs: remove inode::i_crypt_info ceph: move crypt info pointer to fs-specific part of inode ubifs: move crypt info pointer to fs-specific part of inode f2fs: move crypt info pointer to fs-specific part of inode ext4: move crypt info pointer to fs-specific part of inode fscrypt: add support for info in fs-specific part of inode fscrypt: replace raw loads of info pointer with helper function Link: https://lore.kernel.org/20250810075706.172910-1-ebiggers@kernel.org Signed-off-by: Christian Brauner <brauner@kernel.org> |

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
