Reproducible with 1.20 or not?

not reproducible at non-musl-images (musl isn't regularly scheduled here at the tinderbox b/c musl was not matured enough last time it was discussed)

[Comment 10 Matthias Schwarzott 2024-01-19 08:11:49 UTC]

I think this is fixed in sys-kernel/linux-headers-6.2 with commit defbab270d45e32b ("include/uapi/linux/swab: Fix potentially missing __always_inline") see [1].

This fixes a potentially missing definition of __always_inline.
The original report used sys-kernel/linux-headers: 5.6

@Toralf Is it possible to retest this issue? Otherwise I would just resolve it.
