Subject: all compressed kernel when determining range
|
||
|
|
Upstream: no
|
||
|
|
|
||
|
|
Extracted from 0.9.7 patch 'oprofile-0.9.5-buildfixes.diff'.
|
||
|
|
|
||
|
|
This needs further investigation as purpose is unclear, since compressed image
|
||
|
|
isn't supported by underlying sampling code.
