Dear folks,

on the nilfs TODO list i find:

- writable snapshots

This sounds like a fun feature. Would you like to have 1) multiple writable 
and snapshotable heads? 2) support updating a snapshot or 3) support 
writing to a snapshot that is lost when unmounted? But how to number 
checkpoints and snapshots then?

- data integrity support

Isn't that already there ? I thought that each block had a CRC? or would 
you like to integrate that into the inode's btree?

- B tree base directory management
- Extent support

Isn't that mutually exclusive? I.e. btree's and extent support? Or are you 
refering to recording extents in a btree; i.e. map block 0->X, 1->X+1, 
2->X+2 to a form of block 0-15 to block X to X+15?

With regards,
Reinoud
