ext2/ext3_dir_entry_2 has a 16-bit entry(rec_len) and it would overflow

Having a max rec_len of 65532 is rather unfortunate, since the dir
blocks always need to filled with dir entries.
Oh, that's right.
65536 - 65532 = 4, and
the minimum ext3_dir_entry size is 8 bytes. I would instead make this
maybe 64 bytes less so that there is room for a filename in the "tail"
dir_entry.
What does "64 bytes" mean?
Do you mean that the following dummy entry should be added
at the tail of the directory block?
struct ext3_dir_entry_2 {
__le32 inode = 0
__le16 rec_len = 16
__u8 name_len = 4
__u8 file_type = 0
char name = "dir_end"
};
Cheers, sho
