Subject: uapi/kernel.h: glibc specific inclusion of sysinfo.h
|
2015-12-02 22:23:22 +00:00
|
|
|
|
|
|
|
|
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.
