Subject: [PATCH] pid1: add env var to override default mount rate limit
|
||
|
|
interval
|
||
|
|
|
||
|
|
Similar to 24a4542c. 24a4542c can only be set 1 in 1s at most,
|
||
|
|
sometimes we may need to set to something else(such as 1 in 2s).
|
||
|
|
So it's best to let the user decide.
|
||
|
|
|
||
|
|
This also allows users to solve #34690.
