Hi Salvatore,

Please don't worry, fsck has checked your device and reported that "Info: No
error was reported", it means there is no inconsistent problem in your image.

Eric has uploaded a patch to replace the unclear message "Info: Fix the reported
corruption." w/ "Info: Automatic fix mode enabled." [1], I guess we will see
the change in f2fs-tools 1.17.0+.

Thanks,
