From: Daniel Gomez <da.gomez@samsung.com>

The uuid_t struct defined in sys/types.h on macOS hosts conflicts with
the one defined in file2alias, resulting in the typedef redefinition
error below. To resolve this conflict, define the _UUID_T and
__GETHOSTUUID_ in file2alias HOSTCFLAGS.

Error:

Is this what Nicolas suggested?
https://lore.kernel.org/lkml/20240807-sexy-roadrunner-of-acceptance-a84bbf@lindesnes/


I thought he suggested replacing #ifdef __APPLE__
with -D_UUID_T -D__GETHOSTUUID_H.


You added -D_UUID_T -D__GETHOSTUUID_H,
keeping #ifdef __APPLE__.

Yes, I think this patch is unnecessary because:

 [1] You can feed "-D_UUID_T -D__GETHOSTUUID_H"
     from the HOSTCFLAGS env variable
 [2] uuid_t may be dropped if I succeed in
     refactoring modpost in the future

Please, shrink this to the valuable ~3-5 lines. No need to repeat the same for
