/*
|

|
|
* The shmid64_ds structure for x86 architecture.
|
||
|
|
* Note extra padding because this structure is passed back and forth
|
||
|
|
* between kernel and user space.
|
||
|
|
*
|
||
|
|
* shmid64_ds was originally meant to be architecture specific, but
|
||
|
|
* everyone just ended up making identical copies without specific
|
||
|
|
* optimizations, so we may just as well all use the same one.
|
||
|
|
*
|
||
|
|
* 64 bit architectures typically define a 64 bit __kernel_time_t,
|
||
|
|
* so they do not need the first two padding words.
|
||
|
|
* On big-endian systems, the padding is in the wrong place.
|
||
|
|
*
|
||
|
|
*
|
||
|
|
* Pad space is left for:
|
||
|
|
* - 64-bit time_t to solve y2038 problem
|
||
|
|
* - 2 miscellaneous 32-bit values
