Please ignore all Patch V19 series. Will resend. Dmitry/Thierry I am using below stable tags in commit message based on V18 feedback to get patch applied to old kernels Git send email considers whole text after Cc as email address and reports badly formatted address. Is there any format that I should follow to specify kernel versions along with stable tag? Cc: stable@xxxxxxxxxxxxxxx # 4.4+ Cc: stable@xxxxxxxxxxxxxxx # 4.20+ Thanks Sowjanya
