In sem_open.c, pad was not initialized when __HAVE_64B_ATOMICS was
|
||
|
|
true. On some arches this caused valgrind to warn about uninitialized
|
||
|
|
bytes when the struct was written to the file system.
|
||
|
|
|
||
|
|
This patch moves the initialization of pad outside of the
|
||
|
|
conditional.
