Subject: [PATCH] 00_menu_auto_hide: Reduce number of save_env calls
|
|
|
8631a2 |
|
|
|
8631a2 |
Normally boot_success will be 1 on every boot (as normally the
|
|
|
8631a2 |
previous boot will have been successful). This means that we end
|
|
|
8631a2 |
up in the code-path to set boot_indeterminate to 0 every boot.
|
|
|
8631a2 |
|
|
|
8631a2 |
So we do 2 separate save_env calls each boot, one for boot_indeterminate
|
|
|
8631a2 |
and one for boot_success. This results in 2 writes to the disk.
|
|
|
8631a2 |
|
|
|
8631a2 |
This commit makes us save both boot_success and boot_indeterminate
|
|
|
8631a2 |
in a single call, reducing the number of writes, this reducing wear
|
|
|
8631a2 |
and tear on the underlying storage.
