some of these had problems getting the right arguments (namely sys_clone())
|
| 310 |
|
|
when they were inline so I made them non-inline until we get problems with gcc
|
| 311 |
|
|
worked out. I need to check with Linus to find out which he wants inline now
|
| 312 |
|
|
since the above comment was written a long time ago.

Once I understand the macro language better this should go away.
