alpha: Fix generic brk system call emulation in __brk_call (bug 29490) |
|
|
|
The kernel special-cases the zero argument for alpha brk, and we can |
|
use that to restore the generic Linux error handling behavior. |
|
|
|
Fixes commit b57ab258c1140bc45464b4b9908713e3e0ee35aa ("Linux: |
|
Introduce __brk_call for invoking the brk system call"). |
|
|
