Subject: Re: ext2/3/4: punch support?

Hi All,

I've actually already started on a patch set for punch hole support in ext4.  I've sent them out on the ltc-fsdev mailing list for review.  I had planned to spend another week or two running it through some more debug cases before sending it to the ext4 mailing list though.
