Subject: [PATCH] fix parse_affinity for CPU numbers greater than 31
|
|
|
9faa00 |
|
|
|
9faa00 |
The function parse_affinity reports wrong results for CPU numbers
|
|
|
9faa00 |
greater than 31.
|
|
|
9faa00 |
|
|
|
9faa00 |
The problem is caused by the function bitmastlist which parse_affinity
|
|
|
9faa00 |
calls. The fix treats the inpput line as a long hexbitmask instead of an
|
|
|
9faa00 |
array in order to produce correct results
