If anyone has any objections, please let me know. ------------------ From: Paulo Alcantara [ Upstream commit a13ca780afab350f37f8be9eda2bf79d1aed9bdd ] When having several mounts that share same credential and the client couldn't re-establish an SMB session due to an expired kerberos ticket or rotated password, smb2_calc_signature() will end up flooding dmesg when not finding SMB sessions to calculate signatures.
