However, it actually represents the struct data type. To accurately redefine the data type, some adjustments have to be made to the address alignment code. It involved refactoring the common alignment code initially, followed by updating the structure's definition. Finally, the XTS alignment is now performed early in the process, rather than at every access point. This change was suggested during Eric's review of another series intended to enable an alternative AES implementation [1][2]. I viewed it as an enhancement to the mainline, independent of the series. I have divided these changes into incremental pieces, making them considerably more reviewable and maintainable. The series is based on the cryptodev's master branch: git://git.kernel.org/pub/scm/linux/kernel/git/herbert/cryptodev-2.6.git master Thanks, Chang [1] https://lore.kernel.org/all/ZFWQ4sZEVu%2FLHq+Q@gmail.com/ [2] https://lore.kernel.org/all/20230526065414.GB875@sol.localdomain/ Chang S.
