Hi Sheng,

Check extra_attr feature for inode. If it is corrupted, remove the

Could you check the patch:
[PATCH] fsck.f2fs: fix to do sanity check with extra_attr feature
Would it better to do sanity check with it in fsck_chk_inode_blk? since it is
about consistence of inode instead of nid.
Agree. And the patch has already checked the value of i_extra_isize, so this one
can be dropped :-)
Thanks
Thanks,
