linux: use statx for fstat if neither newfstatat nor fstatat64 is present
|
||
|
|
|
||
|
|
LoongArch is going to be the first architecture supported by Linux that
|
||
|
|
has neither fstat* nor newfstatat [1], instead exclusively relying on
|
||
|
|
statx. So in fstatat64's implementation, we need to also enable statx
|
||
|
|
usage if neither fstatat64 nor newfstatat is present, to prepare for
|
||
|
|
this new case of kernel ABI.
