This hierarchy supports Linux systems using the new
|
|
asm-generic/unistd.h, which removes many familiar old syscalls. For
|
|
example, to implement open(), newer Linux architectures require glibc
|
|
to invoke the __NR_openat syscall with AT_FDCWD. This hierarchy
|
|
provides all those implementations.
|
|
|
|
It also provides support for 32-bit platforms using the 64-bit kernel
|
|
syscall APIs, as the 32-bit ones are no longer provided. Note that
|
|
newer ILP32 environments (x32 or AArch64:ILP32, for example) are
|
|
converting to use more 64-bit types in kernel syscalls, so that aspect
|
|
of this support is in more flux as of this writing.
