- From: David Heidelberger <[email protected]>
- Subject: uapi/kernel.h: glibc specific inclusion of sysinfo.h
- including sysinfo.h from kernel.h makes no sense whatsoever,
- but removing it breaks glibc's userspace header,
- which includes kernel.h instead of sysinfo.h from their sys/sysinfo.h.
- this seems to be a historical mistake.
- on musl, including any header that uses kernel.h directly or indirectly
- plus sys/sysinfo.h will produce a compile error due to redefinition of
- struct sysinfo from sys/sysinfo.h.
- so for now, only include it on glibc or when including from kernel
- in order not to break their headers.
