There are several issues in sanity_check_inode(): - The code looks not clean, it checks extra_attr related condition dispersively. - It missed to check i_extra_isize w/ lower boundary - It missed to check feature dependency: prjquota, inode_chksum, inode_crtime, compression features rely on extra_attr feature. - It's not necessary to check i_extra_isize due to it will only be assigned to non-zero value if f2fs_has_extra_attr() is true in do_read_inode(). Fix them all in this patch.
