Remove internal usage of extensible stat functions
|
|
|
00c0d4 |
|
|
|
00c0d4 |
It replaces the internal usage of __{f,l}xstat{at}{64} with the
|
|
|
00c0d4 |
__{f,l}stat{at}{64}. It should not change the generate code since
|
|
|
00c0d4 |
sys/stat.h explicit defines redirections to internal calls back to
|
|
|
00c0d4 |
xstat* symbols.
|
|
|

|
|
|
00c0d4 |
Checked with a build for all affected ABIs. I also check on
|
|
|
00c0d4 |
x86_64-linux-gnu and i686-linux-gnu.
