Subject: [PATCH 21/22] cpuplugd: fix reading the size of /proc/sys/vm/cmm_pages
|
||
|
|
|
||
|
|
Description: cpuplugd: fix fscanf file handling in get_cmmpages_size
|
||
|
|
Symptom: cpuplugd was not able to correctly read the size of the
|
||
|
|
/proc/sys/vm/cmm_pages file. This prevented cpuplugd from using
|
||
|
|
the cmm feature correctly.
|
||
|
|
Problem: The code checked for the wrong return code (!= 0 instead of ==0)
|
||
|
|
Solution: Check for the right return code in the get_cmmpages_size error
|
||
|
|
handling function.
