Subject: [PATCH 2/5] monitor: refactor checkpoint update
|
|
Git-commit: cf87fe75fd83dac008ea116c2c52ec69783fdf6a
|
|
Patch-mainline: mdadm-4.3+
|
|
References: jsc#PED-7542
|
|
|
|
"if" statements of checkpoint updates have too many responsibilties.
|
|
This results in unclear code flow and duplicated code.
|
|
|
|
Refactor checkpoint update code and simplify "if" statements.
