Failed to compile due to missing <linux/blkdev.h> header with liburing-2.9?

Failed to compile due to missing <linux/blkdev.h> header with liburing-2.9?

[Qu Wenruo]

Hi,

Just find out that fsstress no longer compiles on for-next (v2025.02.02)
, patches-in-queue (a494849fb48dc6b276c2a1784d6ff66c731e5572) nor master
branchs (8467552f09e1672a02712653b532a84bd46ea10e)
All fails with the following error:

```
Building ltp
     [CC]    fsstress
In file included from /usr/include/liburing.h:17,
                  from fsstress.c:30:
/usr/include/liburing/compat.h:11:10: fatal error: linux/blkdev.h: No
such file or directory
    11 | #include <linux/blkdev.h>
       |          ^~~~~~~~~~~~~~~~
```

This seems to be a change in the liburing headers, as v2.8 still
compiles fine.

Is there something wrong with header change?

Thanks,
Qu

Are you on arch linux? They messed up their packaging.

Thanks for confirming, will report back to downstream.

Forgot to link it, but also see:

https://github.com/axboe/liburing/issues/1341

which is the same issue on Arch. They compiled the library against
different heads than the version they are installing with, which
caused the issue. They just need to fix their liburing package.
