Subject: [PATCH 2/3] uapi/libc-compat.h: do not rely on __GLIBC__
|
|
|
|
Musl provides the same structs as glibc, but does not provide a define to
|
|
allow its detection. Since the absence of __GLIBC__ also can mean that it
|
|
is included from the kernel, change the __GLIBC__ detection to
|
|
!__KERNEL__, which should always be true when included from userspace.
