Hi, Please ignore other patches about clone testcases and just focus on v3.thanks.

Hi zhanglianjie, > Hi, > Please ignore other patches about clone testcases and just focus on > v3.thanks. FYI you can register on our patchwork instance [1] with email you use for sending patches and update status of your patches (e.g. set patches to be ignored to "Superseded" or "Changes Requested"). Kind regards, Petr [1] https://patchwork.ozlabs.org/register/
Oh thank you. ^_^ On 2021-09-23 17:05, Petr Vorel wrote: > Hi zhanglianjie, > >> Hi, >> Please ignore other patches about clone testcases and just focus on >> v3.thanks. > > FYI you can register on our patchwork instance [1] with email you use for > sending patches and update status of your patches (e.g. set patches to be > ignored to "Superseded" or "Changes Requested"). > > Kind regards, > Petr > > [1] https://patchwork.ozlabs.org/register/ >
> Oh thank you. ^_^ FYI you'll be able to change state of your patches. But in cases like this it helps us to handle the queue (we're always late).
