`glibc` 2.36 `sys/mount.h` incompatibility with `linux/mount.h`

[BurningEnlightenment]

Building llfio with glibc 2.36 fails due to detail/impl/posix/storage_profile.ipp including linux/fs.h (including linux/mount.h) and detail/impl/posix/statfs.ipp including sys/mount.h:

This new incompatibility has been documented in the glibc wiki. According to this mailing thread the glibc maintainers are aware of this and will likely workaround this within the glibc sources in a few weeks. Currently this only affects rolling linux distributions living at the bleeding edge like Arch Linux.
So I don't think it's worth to be patched here.

The situation has been resolved upstream (see commit on master and cherry-pick on 2.36 release)
