Hi!
Forwarding a downstream report from https://bugs.gentoo.org/938569.
xfs_fs.h's xfs_getparents_next_rec relies on an implicit void*-to-T*
cast which is legal in C, but not C++.
It fails like so when a C++ project tries to use the header:
```
/usr/include/xfs/xfs_fs.h: In function 'xfs_getparents_rec* xfs_getparents_next_rec(xfs_getparents*, xfs_getparents_rec*)':
/usr/include/xfs/xfs_fs.h:915:16: error: invalid conversion from 'void*' to 'xfs_getparents_rec*' [-fpermissive]
915 | return next;
| ^~~~
| |
| void*
```
It came up when building libktorrent.
thanks,
sam
