The rationale +for this is that there's no point in marking a block as bad, because good +blocks are also 'marked as bad' (in the OOB BBM sense) under normal usage. + +Instead, the driver relies on the bad block table alone, and should only perform +the bad block scan on the very first time (when the device hasn't been used). diff --git a/Documentation/networking/ip-sysctl.txt b/Documentation/networking/ip-sysctl.txt index 5de03740cdd5..ab42c95f9985 100644 --- a/Documentation/networking/ip-sysctl.txt +++ b/Documentation/networking/ip-sysctl.txt @@ -1088,6 +1088,12 @@ igmpv3_unsolicited_report_interval - INTEGER IGMPv3 report retransmit will take place.
