5.19.0-35-generic removed genhd.h?

[kattantak]

I just tried to recompile on the newest kernel what I got with ubuntu update

dattobd/src/includes.h:13:10: fatal error: linux/genhd.h: No such file or directory 13 | #include <linux/genhd.h> | ^~~~~~~ compilation terminated.

It seems for me this header is not exist any more in the newest kernel on ubuntu. Please investigate. Thank you.

Most of the genhd stuff moved to blkdev.h

Hello @kattantak we have added support for kernel 5.19, you can check it out

[kattantak]

Hello. Building smoothly on 5.19. Thanks for the update.

[kattantak]

Unfortunately for some reason it is not able to create snapshots. Do you have any idea why or how I can check what can be the problem? Thanks

@kattantak I will look into that, are you able to tell me which commit did you build? Also are you using LVM on your machine?

[kattantak]

I am using the latest commit as freshly cloning the repo. "git clone https://github.com/datto/dattobd.git" Not using LVM.

Meanwhile my ubuntu updated to 6.2.0-33-generic and I cannot comply the module again. make[2]: Entering directory '/usr/src/linux-headers-6.2.0-33-generic' warning: the compiler differs from the one used to build the kernel The kernel was built by: x86_64-linux-gnu-gcc-11 (Ubuntu 11.4.0-1ubuntu1~22.04) 11.4.0 You are using: gcc-11 (Ubuntu 11.4.0-1ubuntu1~22.04) 11.4.0 CC [M] /home/mike/dattobd-git/dattobd/src/bio_helper.o /home/mike/dattobd-git/dattobd/src/bio_helper.c: In function ‘dattobd_set_bio_ops’: /home/mike/dattobd-git/dattobd/src/bio_helper.c:184:9: error: implicit declaration of function ‘bio_set_op_attrs’ [-Werror=implicit-function-declaration] 184 | bio_set_op_attrs(bio, op, op_flags); | ^~~~ cc1: some warnings being treated as errors make[3]: [scripts/Makefile.build:260: /home/mike/dattobd-git/dattobd/src/bio_helper.o] Error 1 make[2]: [Makefile:2026: /home/mike/dattobd-git/dattobd/src] Error 2 make[2]: Leaving directory '/usr/src/linux-headers-6.2.0-33-generic' make[1]: [Makefile:17: default] Error 2 make[1]: Leaving directory '/home/mike/dattobd-git/dattobd/src' make: [Makefile:24: driver] Error 2

I just going to compile from source because ubuntu install not working to me.

[Swistusmen]

we're currently focusing mostly on kernel 5.19. Tested building on kernel 6.1. So 6.2 is not covered with tests, but we're going there. If you find any solution/ workaround I encourage you to share it with us either by creating PR or suggesting solutions. Thanks for you input

[kattantak]

OK. no rush with this. Thanks.
